Ok so me and the husband have been looking into building/buying a coop. And we was wondering what the appropriate dimensions should be to house 11 chickens with the opportunity to add quite abit more. So far our dimensions are 10'x6'x10' with a nesting box of 1 1/2'x3'x4' with 6 boxes separated. But we will also be adding a chicken door to allow our chickens to enter an old covered chain link dog kennel that is 6'x6'x10' additional run. Would this be enough space to house 11 chickens comfortably and still allow some more room for additional chicks this spring?
