My Coop
My Coop
So last spring my wife said: "We're getting chickens." And I was like: "Ok...?" Fast forward some weeks her finding out how to mail order some day-old chicks, picking which breeds, doing reading about the coop, how to take care of them, etc. I did grow up on a farm and we had few chickens but now I had to really know what I was doing. Well yeah, I can make it up as we go. How hard can it be?

Sooner than I realized the box arrived and we had newly hatched chicks in the bath tub. I guess I should start building the coop.

Next few days I read all possible articles and forums and any plans I could scour what kind of coop, how big, what kind of run, anything at all people had done with their setup. But none really caught my attention and as with most of my projects, I was going to build it from scratch and just see what comes out of it at the end. Couple things were certain, there was going to be some sawdust and several trips to hardware stores. I was ok with that. And I already missed the timeline of having the coop ready before you get the chicks.

First the location. I first thought of a free-standing, somewhere within the acre of a yard we have. Our property is completely surrounded by forest, so any place is as good as the other. My wife suggested why not just attach it to the shed, which I had built a while ago. After careful pondering I could not come up with anything better.

Next, material list. What list, I didn't even know what I was going to build. It needs floor, walls and a roof. And maybe a door. Oh and nesting boxes. And maybe some kind of a light, chickens need light for 15-16 hrs a day to lay eggs. The shed has it's own 20Amp circuit in it with a breaker box, that should make it easy.

So lets begin with the floor. Rough measurements of the space available is 6' X 11' and I want to make it raised off the ground, making the space underneath available for the chickens at any time. The soil drains extremely well and gently slopes towards the shed and the front of it, so I don't need to worry muddy conditions too much. I did put a layer of coarse sand underneath already and will do within the run once that's complete.

The shed is 12'x16' and the actual floor of the coop came to 6'3"x11'7" as I didn't want to remove the window. I've since replaced that chickenwire with 1/2" hardware cloth along the edge of the shed, buried about 1.5'.
WP_20170729_17_45_29_Pro.jpg

And then everything leveled, floor boards in place and seams caulked.
WP_20170730_19_02_44_Pro.jpg


Then the walls. Ok, I had no clue how to proceed. I did want to make use of some 4x6's which I've had for years. So I measured the slope of the roof and how high I could make the long side and raised the beams on top of 2x8's at the end and shorter 4x6 in the middle.
WP_20170806_12_08_06_Pro.jpg


In my haste I forgot to take pictures of the side wall construction. They were really simple framed with 2x4's along the edge, so those walls are just 2" thick with the siding. I'll explain more about them further down.
The two large openings I planned for nesting boxes, but I also wanted to be able to open them completely. So I made two of these, one with 5 nesting boxes, another framed exactly the same but without boxes in it.
WP_20170819_10_45_48_Pro.jpg


Nesting boxes are 12"x12"x15" in size with the 1x4 keeping the bedding in.
WP_20170819_10_46_32_Pro.jpg


For the roofing I'm using just off the shelf shingles. Right side extends 3' and left side 4' over to give more rain cover. The wall with nesting boxes and the one next to it are both mounted onto the 4x6 beams with 4" hinges, so they can be raised upwards all the way to the roof. Maximum clearance for spring cleaning.
WP_20171002_17_13_56_Pro.jpg


If you wondered what was the plexiglass thing up there for? It's for the skylight of course! And if I made one, might as well make 2 of them. Why? Because I've had some 1/4" Acrylite sitting around with no better use for it.
WP_20171002_17_23_52_Pro.jpg


Sideview of the door and access hatch for the girls. The roof is supported by 2x6x10' beams, giving nice overhang. I also got some 1/8" sheeting and covered all the framing with it. This leaves no flat surfaces for the dust to gather and it frankly looks much better.
WP_20171002_17_17_38_Pro.jpg


All the vents have 1/4" aluminum mesh on the outside and bug screen on the inside. Located above both doors and along long wall between each 2x6's.
WP_20171002_17_22_11_Pro.jpg


And the view from the door opening on the other side. The girls are definitely wondering if this things is ever getting finished.
The floor is fully covered in linoleum. Just couple remnants I had leftovers and put to good use. Already have been praising how easy it is to scrape things off the floor when cleaning.
As soon as I saw those bulkhead lights, I knew there were perfect for the coop. I have LED bulbs in them so they will never get hot to harm the girls, one being within reach from the perch. It also allows them easy access to any flying bugs in the evenings if any get inside the coop. Timer switch is located inside the shed, where I store the feed and bedding. Just a note, I framed this wall exactly mirroring the other, so that I can easily open another access hatch to this end if I need to.

Closer view of the nesting boxes.
WP_20171002_17_18_14_Pro.jpg

The perch structure is just simple pine 2x4's, which I routed with 1/2" radius on all edges. I might modify this or make something totally different but they loved it right away.
WP_20170906_18_13_18_Pro.jpg


Perhaps the longest time I spent on figuring what the final watering system should be. These drink cups are amazing and the girls learned them in just couple of days. They are glued onto regular PVC pipe which I painted black. You can also see how close the bulkhead light is to the perch and attracts any flies or mosquitoes to their quick doom. Both corners have 15Amp outlets and on this one I have a dimmable LED nightlight. Yeah I know, we spoil them.
WP_20180113_16_07_34_Pro.jpg


Last thing I added is steps. Left side leg is about 5" lower than the other. The ramp has hinges, which allows me to lift it out of the way when I need to take a wheelbarrow to the other side of the coop. I got couple of those LED strings on after Christmas sale and it lets the girls roam in the run at dusk if they want to.
WP_20180113_16_35_55_Pro.jpg


The steps are free standing for easy removal. It is supported by flat bars with a slot that the 1/8" bar slides into. You can see how I mis-measured at first and had to weld another piece to extend it.

That's all the pics I have for the coop, I'll make another post for the run and its fencing. If you would like more details about any of the features I came up with, please request it below or send me a note.
 
Nice Job. We are getting ready to expand our coop - actually build a new one. We have the cutest chicken house - good for about 16-18 chickens - but we just inherited 14 more chickens - so decided to build a bigger building to handle all of them. Will use some of your ideas!! - By the way, the two groups of chickens are separated - have been apart for 3 weeks now - but both groups get out & graze on our 15 acres of pasture. They haven't mingled yet - but we have a whole summer......
 
Looks great so far! How many sq ft of ventilation is in there for how many chickens? I'd maybe add more ventilation if possible, but I think I probably overkill it on that front.
 
Hi Rose,
It has 9 vents, each 4"x18", couple could be a bit more. That should come up about 4.5 sqft. With 8 hens there has been no issues with odor or fumes with biweekly cleaning. Now with the pullets in there, it'll be total 18 chickens. I will need to keep an eye on it for sure.

Definitely keep an eye on it. As you're obviously very handy you'll be able to find ways to add more ventilation if needed. Really do like the addition of skylights as there wouldn't be much natural light in the coop without those.
 
Thanks all for your comments. I'm always curious how others engineered through their particular dilemmas and want to learn without making too many mistakes.

Here is the current status of the coop and the run:
I originally thought of making a total of 3 skylights to it, but realized that was a bit too much. They do add a nice amount of sunlight and I'm glad I went through the hassle of putting them in. And the LED bulbs I use inside are also Daylight 5000K if I recall right.
Our chocolate-tan minpin Hazel is there checking out what the hens left behind. To the left corner I will put a rain barrel and a spout from the gutter to it.
The right side open area is 10'x23' and the "front" including underneath the coop is 11'x18.5'. That makes total run to 433.5 sqft, just little over 48 sqyd. Add that the inside area of 66 sqft and few inches.

I wanted to show what it looks like with the side panel opened up.
WP_20180408_12_06_54_Pro.jpg


And here is what the side vents look like. I closed these hinged covers during the winter nights when it dropped below freezing, which helped to keep the warmer air in.
If I need to add more ventilation now that we've added the new chicks into the coop, I might consider a rooftop vent next.
WP_20180408_12_09_00_Pro.jpg


For the fencing, I'm using 1/2" hardware cloth. It is buried about foot and a half at all sides. Posts are 10'x1 1/2" galvanized electrical conduit, easily available at your local hardware store and cheaper than what the 8'x1 5/8" chainlink posts cost. Post footing mold is 6" galvanized steel furnace ducting.
WP_20180321_17_59_33_Pro.jpg


Here are the mold pieces taken out after the concrete cured. Fence is embedded through the concrete on the outside of the post.
WP_20180408_12_10_29_Pro.jpg


Right side roof corner needed some support, so I made this triangle bracket for it.
WP_20180408_12_00_32_Pro.jpg


It's just two pieces of the same 1 1/2" conduit. I put the ends onto a vice and squished it flat. I welded on a piece of 1/8"x1" flat iron and then cut other ends at about 30' angle and welded together.
WP_20180225_14_49_26_Pro.jpg


I never guessed I would invent a new use for duct tape with this project.
For the top supports I'm using 1" galvanized electrical conduit. To connect them to the posts, I attached 1 3/8" aluminum rail ends. Duct tape made the perfect filler to make it a snug fit.
WP_20180219_14_56_45_Pro.jpg


Then I drilled holes and drove a 2" galvanized nail through. Then cut it leaving about 1/4" stub.
WP_20180219_15_01_33_Pro.jpg


Then bean it flat.
WP_20180219_15_03_28_Pro.jpg

Here's 3 supports that I welded flat bars to the ends.
WP_20180219_15_38_54_Pro.jpg


And they give perfect support for the post. To attach rail ends, I used galvanized 1 5/8" Brace bands which squeeze really tight fit to the posts.
WP_20180219_16_42_05_Pro.jpg


For the gate door, I used 1 1/4" galvanized electrical conduit making it just a tad lighter. 10' poles made a good 4'x6' size. Hardware cloth is attached by riveting 3/4"x1/8" aluminum strips on the inside, clamping the cloth in between it and the pipe. This left corner will also get another triangle support for the roof so that I can get rid of that 2x4 beam in the way.

You've certainly got some fabrication skills!
Huge roof overhangs are awesome for your rainy climate.
Nice job!

I closed these hinged covers during the winter nights when it dropped below freezing, which helped to keep the warmer air in.
Leave them open......ventilation is more important than 'holding heat'.
