Wednesday, June 6, 2018. My heart was broken for some time. So I wept, made dolls and needle-felted. Surprisingly, my heart healed! Suddenly, I stopped all needle-felting to grow an urban organic food forest for my family. We decided to grow chickens. So I designed a coop for them. My children helped me build the coop. This is our story. I hope you can use our design, improve upon it and build yours. If you do so, please share with me, we would love to see it!

love, from our garden to yours! Jzin

Our garden is in Costa Mesa, (Orange County), Southern California, Zone 10B, 10 minutes or so from the Pacific Ocean. We live in an urban residence with a lot size of 6,720 sq foot, including the house, garage and various cemented areas.

What I needed my Chicken Coop to do

These were my goals for my DIY chicken coop!

  1. Organic, non toxic.
  2. To protect the chickens from predators such as mice, rats, garden cats, opposums, possible coyotes in the City of Costa Mesa.
  3. Southern California summer heat wave. To provide cool shade, good air flow.
  4. Sunshine, fresh air: good ventilation.
  5. A vision of romance and beauty!
  6. This coop is designed to be an organic compost generating machine. We want our chicken coop to make compost for our garden. Shad in Guatemla presents the BEST video on Youtube (below) on active decay cycle chicken coop. Wide and easily accessible doors to make harvesting finished compost easy: roomy front door, back gates swing out for easy access to that black gold!
  7. Low maintenance. Coop can confine deep bedding. With deep bedding, I do not have to clean the coop daily (or ever).
  8. A coop that is cool in the summer and warm in the winter: In winter, we will pile lots of hay and composting matter right under the hen house. Composting chicken coop generates heat in winter: warmth for chickens, by spring we can harvest ready compost for the garden.
  9. Protect my hens from winter rain.
  10. A heat source (compost beneath the hens) to keep the hens warm in winter.
  11. Can grow beautiful vines directly on an area fertile with chicken coop, to produce shade for chicken, beauty, eggs, fruits and veggies.
  12. Enough room to partition off new chickens if needed to add new members to my flock.

My other needs for the DIY building project:

  1. The project is to allow each child to actively participate in designing and building.
  2. Limitations: my paltry carpentry skills and materials accessible to me as an urban resident and person without a moving truck. I have to learn how to use a chop saw.

  • Walk-in chicken coop, low roof for a short Asian woman.
    • If you are other than a short Asian woman or similar to that…
    • If you are tall, perhaps you could add 2 T-posts on each side of your cattle panel arch, to raise the coop higher, so you do not get bonked on the head when you are inside the coop. Remember, the level of the flooring changes through the season. The flooring is low in spring after you harvest the compost. Then you add your composting layers periodically through the seasons and hopefully by winter, your coop floor is high and the decomposition will keep your hens warm in the cold months. That said, if you are tall, you may want to raise the coop ceiling.
    • I do suggest you add wire mesh as wells instead of solid wooden panels, this way you get good air flow.
  • The foot print is about 9 foot x 9 foot.


Building the Base/Frame

I wanted a coop with an open bottom floor so that earthworms, bugs and soil microbes could access the actively decaying compost that is the floor of my chicken coop. I also wanted carbon-rich deep bedding, so the sides(walls) and door threshold of the coop are necessary to keep the deep bedding in.

I choose to use untreated redwood lumber for nontoxic, longer-lasting coop. Treated lumber is cheaper but may contain toxic chemicals.

Sunday, April 16, 2017. We started by building a 9 ft x 9 ft redwood lumber frame as a base for our coop (not shown).

Photos: My children V, E and D helped attach the 2 cattle panels, arranged side by side, to two additional pieces of 2 x 6 redwood lumber.

We used two of these cattle panel fencings from Tractor Supply Company, 16 ft long x 50 inches height.

Once the ends of the cattle panels were attached to 2 x 6 supports, Patrick and Bisser carried the cattle panels and inserted them into the square frame.

Voila! By the very evening we have a facsimile of a house! Hurray! That was quick!

Later on, the lumber attached to the cattle panels were screwed into the square base for added stability.

The Front of the Chicken Coop

May 9, 2018. Door frame, threshold and coop-front horizontal support 2 x 4 bars have been installed.

The threshold of the door is high because we plan to use deep bedding for composting. The high threshold makes it possible to swing open and close the door without having it stuck into the deep bedding on the ground.

I made a decision for the door to swing inwards. I considered if I had to enter the coop at some point without the hens leaving, the inward swinging door may help deter chickens escaping.

I also made a pull string on the inside of the coop that will unlatch the front door, so that you can get out of the coop in case you get locked inside by mistake.

Note, the weather is warm enough now for our now older chicks, so we set up make-shift coops inside the unfinished coop for them to live in when they are not free-ranging.

We used these self-drilling wafer head screws for easy attachment of 1/2 inch hardware cloth onto door frame and other wooden supports.

We buried 1/2″ hardware cloth into the ground to prevent burrowing predators from entering the coop.

Next, we cut out pieces of hardware cloths, using special wire cutters from Home Depot and draped the coop with hardware cloth to prevent predators from entering.


Securing the hardware cloth to the cattle panel and trimming off excess zip ties is a fun job that can involve small children.

It’s a two person job: One person works from inside the coop, the other feeds the zip ties from outside the coop.

My kids help zip tie  the hardware cloth to the cattle panel frame, then trim off the excess zip ties with scissors.

Hen House: Windows for Egg Collection

Photo: April 21, 2020.

If a chicken coop is like a house, the hen house is like the bed room. The rest of the coop is like the living room. The bed room (hen house) should be dry, cozy, high up, private, have nice air flow and safe for the hens.

I bought 2 large plywood boards (thank you Danny for helping us haul that home in your truck) as the two walls of the hen house.

I bought a $5 jig saw from garage sale and proceeded to cut the 2 pieces of plywood into semicircles (as 2 walls of hen house) in the spirit of the hobbits. Orange Home Depot buckets served as supports to elevate the plywood for cutting.

Roost bar(s), hung high up in the hen house, for the hens to perch on and sleep at night. I imagine hens may find rounded roosts more comfortable to their feet, as opposed to rectangular beams.  I used 2×2 redwood lumber for durability but later considered using as roost bars: moringa tree trunk, a tree branch, rounded pole for closet, any rounded beams.

I wanted the roosts to be hung and removable, for when I needed to enter the coop for cleaning or to access a chicken.

My removable roosts: I screwed in a 2″x3″ or so piece of thin plywood tab to each end of a 9 foot long 2×2 red wood lumber. The added tabs on each end of the lumber will hook onto the cattle panels, suspending the roost above ground.

Patrick was renovating our kitchen this summer, so I squirreled away some old cabinet doors to use as egg-harvesting windows for the back of the hen house!

Note: we carefully wrapped all possible predator entry points with 1/2 inch hardware cloth.

170508 windows of coop L 9059

Post script on the egg harvesting window:

For the first year or so, my chickens do not lay eggs here. They lay eggs in the natural passion fruit vines nest in my “passiflora jungle” chicken run. We ended up having to do “Easter Egg Hunts” in our passion fruit chicken forest to harvest eggs. Now in 2020, the hens finally approve of the nesting boxes and use them more routinely.


My chickens adhere strictly to early bedtimes without me enforcing it. Whenever it gets a little dark, they run to go home to the hen house to sleep. We can spy on them through this hole without disturbing them!

From the front view of the hen house, the wall consists of a double door (see below). The smaller one can be left open in hot summer for chicken and air to flow through. The larger door makes it easy for humans to enter the hen house to clean and do other potentially necessary work.

Springs were attached onto windows for automatic closure, to prevent predators from entering. See below, view from inside the hen house towards the back of the coop.

Installing Corrugated Roof for the Hen House

April 17, 2018. It is spring break. Nunu and I went to Home Depot to shop for the nicest color for the hen house roofing.

Uncut, the polycarbonate roofing piece is 10 foot tall. Thank you Danny for helping us bring the piece home in your truck!

Mermaid green. That’s it. That’s the one. $14.97 one piece.

170417 10 foot polycarbonate corrugated roofing for chicken coop hen house 8788

The 10 foot roofing was cut into 4 pieces of 2.5 ft each.

One cattle panel is 16 ft long. Our hen house is sited in the back of the chicken coop. The roofing is to cover the hen house from the ground on one side of the coop, up to the top of the coop and down to the other side of the coop. See photo below.  This way the hen house is completely protected from rain.

The roof will shelter the chickens from rain and the arch shape will score you points with hobbits and gnomes.

Securing corrugated roofing to the coop:

  1. I cut cheap 2×2 wooden beams into about 2 foot long pieces.
  2. I zip tied those support beams to the cattle panels at locations where the roofing panels will meet.
  3. I screwed in roofing panels sequentially onto the 2×2 support beams.

Roosting Bars and Nesting Boxes inside the Hen House

April 28, 2017. I eyeballed the height of the roosting bars and nesting boxes, to make it easy for the youngest family member to harvest eggs in the morning.

Most hens love to cuddle and sleep on the roost at night. Some prefer to sleep in the nesting boxes. April 2018 photo:

December 2017.


It would have been ideal if I had used round diameter tree branches as roosting bars. However at that time our moringa trees where still to young to be harvested, so we used 2 x 2 lumber instead.

by tagging in an extra piece of plywood to the ends of 2×2 roost bars, they were rendered movable. We can hook the roost bars onto the cattle panels or unhook the for easy removal.

Deep Bedding:

Soil Fertility, Composting Heat in Winter, Low Maintenance

The chickens are basically living atop a compost pile. We add alternating layers of green and brown organic matter to the coop floor and water the layers periodically to keep it damp for good compost to happen. We are careful cover up kitchen waste with leaves, hay or wood chips to prevent attracting flies.

We want our composting chicken coop to generate heat for the hen house in winter, thus keeping our hens warm. By spring, we would like to harvest that compost to use for our garden.

The floor of the coop rises and drops according to season. In early spring, the floor is the lowest because we would harvest all the rich, organic, black, earth-worm filled compost to grow heirloom tomatoes and other foods at home. By winter, the flooring/deep litter is the highest, (We would have been adding materials to the deep litter since spring) so the composting will keep the hens warm.

Here are some of the beddings we have used as deep litter:

  • Most bottom layer (takes longest to decompost): Rough branches and leaves from neighbor Craig’s loquat tree
  • Peterson’s Tree Trimming. Free wood chip mulch. If you have guests or someone you need to impress and your coop floor looks messy – cover with wood chips or hay. Pronto! They look more neat and presentable!
  • Flattened cardboard boxes coz earthworms love them!
  • Alena and Patrick’s gift of dry straw
  • Gaby’s yard trimmings: fluffy leaves with pink bougainvillea
  • Kathy’s freshly mowed grass! Must be organic.
  • Straw, bought from The Feed Barn when I really need to cover too much nitrogen-rice kitchen scraps in a hurry.
  • Dried leaves scavenged from the city.
  • Organic produce salvaged from our favorite local grocery store and organic restaurant dumpsters to feed the chickens.
    • This works only if you have a lot of carbon-rich materials to cover the nitrogen-rich, flies-attracting materials.
    • We had mountains of carbon-rich wood chips from the tree-trimming service to cover the materials, to avoid breeding houseflies. I also get organic yard trimming (dry leaves, flowers, dry grass) from Gaby and Felix to cover these.
    • Be careful to cover your nitrogen-rich scraps within 20 minutes or so to prevent flies!
    • I love adding organic produce waste (otherwise destined for landfill) because I have been rewarded with so much rich compost by the next growing season.
  • We even toss in dandelion, mallow and weeds here! (Don’t follow everything I say…)
    • The thinking is that if the weeds sprout, they provide nutrition for the hens.
    • If they do not sprout, by the end of the season, they become black compost for my garden.
    • That said, I do have some dandelions growing in my garden bed. Could it be from this practice?
  • Whenever we dump a layer of leaves, it is like Christmas for the hens! They scream with joy as they dive in and look for bugs. That is one of the reasons for keeping chickens.
  • I also seed my deep-litter with big juicy earthworms from my vermicomposter. This way my chicken coop is also a vermicomposter! I water the coop floor periodically to generate moisture for my worm babies. I get tons of baby earthworms and eggs by spring.
  • etc

Caveat: The chicken coop is now basically a compost-making machine that your hens just happen to live on. Just like any other compost pile, it attracts flies, mice and other unwanted visitors.

  • The 1/2 in hardware cloths protects me hens from unwanted visits from mice, snakes, possums, raccoons, etc
  • As for flies, I try to only add nitrogen-rich materials in the colder seasons and cover well within 20 minutes. If you do so in hot summer, you risk attracting a lot of flies unless you cover very well with wood-chips or other carbon-rich materials.

Growing Vines over Chicken Coop for

Beauty, Bugs, Shade and Foods

1904019 coop with cecile brunner L

Photo: April 16, 2019.

I think a decidious food or fragrant rose vine is ideal to grow over the coop. In winter as the sun is low, the dropped leaves will allow more sun to reach the coop.

Vines that I have considered…

  • Fragrant roses.
    • We chose Cecile Brunner rose which is so fragrant (smells like french talcum, so special), prolific, repeat blooming. Most of the stems are *almost* thornless and they make great cut flowers in small cups. Downside: if unpruned, they become lankily octupusly and will grab you as you walk by to harvest eggs. Since I am short, I am unable to prune the top of the coop, thus the roses shoot straight up into the sky!
    • I recommend you try the Lady Banks roses if you want a sigh-inducing once a year proliferation of roses without thorns or fragrance. Nah, go with thorns and fragrance!
  • Loofah gourds.
    • We planted this in 2017. It was too vigorous and engulfed the coop quickly, producing many gourds. The unpruned, overwintered loofah vine was bit too robust.
  • Grapes.
    • Gives lots of shade, leaves are deciduous in winter to let in sunshine. June bugs who come for the grapes will provide extra protein for the chickens.
  • Passionfruit vine.
    • We have 2 beautiful passion fruit vines growing at home, but their growth habits are too vigorous and will engulf the coop in weeks, so we decided against passion fruit for the coop.
  • Black eyed susan vine.
    • Sweet looking flowers, too vigorous, will cover the coop too quickly but does not produce food.
  • Water melon.
    • Needs to be carefully trained, melons supported – I am too short to train the melons to the top. Nah.

April 2018. Vihren harvested a basket of fragrant Cecile Brunner roses, grown from fertile chicken coop poop for his teacher.

190129 Black Compost in the front yard L

This is such a hassle-free coop design. I almost forgot about it. January 30, 2019. Yesterday, my son Vihren and I harvested some dark, rich compost from the bottom of the coop and mulched our winter salad patch in the front yard. Look how black and gorgeous the compost is! WOW!

March 9, 2019. Our front yard salad patch, grown with compost made in the chicken coop. See, you do not need to plonk your chicken coop on a sandy or cement base and diligently scoop poop daily. You can be lazy like me, build a composting coop, toss in leaves and compostable layers, let the hens bless the compost with their scratching and pooping and by the end of the season, you have WOW rich, black, earth-worm filled compost to grow your food!
