Hi. I have a 5' wide x 10' long x 6' tall welded wire dog kennel that I want to use for 4 to 6 full size chickens. I plan to build a wooden coop within the dog kennel. The coop will be off the ground so the chickens will have the whole 5' x 10' area to scratch around in. I figure I need space for three nest boxes in the wooden coop. Wanting feedback on size for wooden portion of coop. Would something 3' wide x 4' long be adequate? Also how high should the coop be (interior chicken space)? Is it important to have less height above nest boxes if so what should that height be? With regard to height of the coop off the ground, I was thinking maybe 3' off the ground would be good. Will have a "ladder" so they can get into their coop. Thanks in advance everyone.
