I found a coop that I'm interested in getting so that I can start enjoying the Backyard Chickens experience. The measurements are: Chicken Coop Dimensions Outside: 82 in(L)x52in(H)x27.5in(W) 2100mm(L)x1330mm(H)x700mm(W) Inside: Coop/House Inside Area is 25.5" x 25.5" Approximately 4.5 sq.ft NEST BOX Inside 21" long x 11" deep Run Area Inside Measurements Total Run Area Is About 64" long x 25.5" deep Approximately 11.3 sq.ft Now, we would like to get Rhode Island Red hens. How many hens would be best and healthy for these dimensions? (Note: They will be allowed to free range at least a few hours a day.) Thanks!
