I built my coop thinking I would be happy with three chickens and never need to expand. It is perfect for my three chickens but not for five; I want two more chickens. The run is 9' x 4' = 36 but is not all usable space since the ladder and food take space. The coop is 4 x 3 = 12. I think 5 chickens might be ok with the coop/run I have but feel it would be much better if I can expand as much as possible and still have it look nice. Does anyone see this coop and have any good ideas on where/how I can add on to my coop?
