I've been meaning to make a new chicken coop and run for a while. We have one, but the coop isn't well designed and the run "runs" north, which leaves it damper and colder than it needs to be a lot of the year.
My building skills could use some work though and I've been curious to try out a chicken tractor. Decided to "just do it" and build a tractor. Didn't really follow any existing design. It's 4 feet by 8 feet.
Wanted to share the build, what worked well, what didn't, and what I'm planning to change. I used a lot of old materials, so there's some random colors and such throughout. I also made some mistakes on fitment, my tolerances were poor, and ended up adding more materials here and there to cover holes.
The chicken egress door ended up turning out really well. It's the door on the side that rotates. Very simple and problem free so far.
I wanted to be able to catch rain water and protect chickens from the elements a little better. It ends up being pretty dark, although no problems laying yet. The rain catch does work and would work better with a cap on the end of the black pipe. Unfortunately, the "clean-out" cap on the side of the black pipe with the chicken nipple leaks. I haven't taken the time to put some kind of thread sealant on it. I did the math and a 4x8 roof is actually plenty of rain water for chickens in a year, if you didn't lose any, etc. For us it'd be something like 500 gallons a year at a minimum.
I wanted to maximize open ground space and elevated the nesting boxes. Of course, they only use one of them. One notable problem is that the chickens roost on top of the boxes. The boxes should be lower than the roosts and the top of the boxes should be covered.
It is very sturdy. No chickens have escaped while it was closed up. The rope going under the bottom was mostly just laziness and will wear out over time. The rope actually broke, but not down there.
Which brings me to the biggest issue. It's too heavy! I knew I'd have to keep weight in mind. I used 3-ply plywood for a lot of it, once I thought of it. I still have some half inch plywood which is overkill and heavy.
When the black pipe has water in it, it's even more. Even without, it adds too much weight. And isn't a reliable enough source of water to be worth using. The roof also adds a lot of weight.
I've been able to pull it with about all of my might. My back went out, so my wife tried to pull it. She couldn't pull it at all.
I'm going to ditch the rain catch and try to lose weight on it however I can. Planning on having a pipe style setup for food and water, to be very easy to refill.
I should've made the door open exposing the eggs first, rather than last. A chicken did get out once through that big door.
Another issue is that especially for these smaller, active birds, it's not much space to run in. But it makes an okay coop otherwise. I've had 8 birds in it for a while which is about the most I'd want.
It did run over a bird once when pulling, but the bird was thankfully okay. A lot of that is because it's so heavy I end up having to yank it to get going over a little mound, etc (our ground is not very flat.) When it's moving slowly and steadily the birds do a good job staying out of the way.
Hopefully this helps someone else on their build, or deciding whether to build/not build one in the first place.
