Hello all, Just got 2 red silkies, they are about 2 months old. Found this site to be valuable source of info. Currently they are in a large box in the kitchen, once I finish the coop they will have the run and the whole back yard to run around and eat all the bugs they want. The coop is 4ft x 3ft and 4ft height, 2 ft off the ground. Does anyone know whats a good number to fit in this size coop that I have. I'm getting answers from 3 to 6. I live on long island, NY and it does get cold in the winter months here. Thanks for all your postings.
