"The Tank" is what my wife calls it.
It's a 10-foot-by-6-foot, metal-paneled, movable coop, with handles, wheels, nest boxes, roosts, and a hardware cloth floor.
Here is The Tank right after being built:
Here it is with my chicks in their movable pasture:
Some of the notable features include:
- Locking double doors for egg collection
- Locking ramp for getting in and out
- Ventilation in the upper peak of the roof
- Roosting space for up to 40 (tightly squeezed) chickens
- 6 nest boxes, including two at 18" by 18" to accommodate my Jersey Giants
- Totally sealed interior via locking doors, hardware cloth on the floors and wheel wells, and sheet metal paneling
- A place to hang a nipple waterer on the inside
- Mountain bike wheels and handles for easy moving
- A hardware cloth floor for easy...er...fertilizing
The walls are 3' and 5' high, respectively. The roof ended up being just about 7' long, and I built in some overhang. It's not that heavy, and with the well-oiled bike wheels, very easy to move. Also, the metal colors match my shed and house.
The complete guide to how I built it, including materials list, is here:
