I think you will want to double the size of your henhouse or make it 16’x8’ and that should accomadate your birds. Why do you keep their feed & water in the henhouse? How large is your run?The actual coop (with food, water, 2 dust baths, heat lamps when needed, and roost) is 8’x8’x8’. Their coop is attached to an outside run that is pretty big, but we will be adding to it this weekend. I was counting the coop separately from their outside run.
