OK, be gentle. This is my first try at chickens. And I have a 4 year old and 6 year old helping me with all stages of coop design, building and chicken care. I was going to build a chicken tractor. Lots of recycled lumber to work with, so that we could have 2 chickens in the backyard. One hen for each kid. Then I decided on 4 hens. That way, if one hen dies, neither kid is left without. Then I decided I wanted the tractor to be larger than most I have seen, so that the kids could go inside to help with feeding and cleanup. Then I bought 6 chicks! And despite our ignorance in all things chickeny, they seem to be thriving. Well, now I have a half coop/ half chicken tractor thing. Too big to be a chicken tractor, too small to be a real coop. I call it the Coo-tor! Over all dimensions, 4ft by 8ft and 4 ft tall. I still have to add some type of roof but the Coo-tor is almost too heavy to move already. I am going to add some heavy duty wheels to see if that helps. In the end, I [plan to let the chickens out in the yard as much as I can, but this will be their primary housing, once they are ready to move outside. But my biggest mistake, I think I am building the hen house side too small for 6 hens. 2ft by 4 ft and 3 ft tall. I am hoping to have two nesting boxes in there and one roost going across the longest side. Too small inside area for 6?
