So I have been trying to get an idea of what I want in a coop. I think I will go with the pvc pipe feeders and waterers to save on feed . I also want to make this as eco-friendly and wallet friendly as possible. Since I am in Ct winters are a concern.I want to make sure i have enough room for about twenty. From these qick sketches does it look like i am missing anything? Should I have more nest boxes or roosts ? is the ventilation ok? i would like mixed breeds like RIR's. Any feedback would be awesome.
