I'm planning to get up to 10 silkie bantams, and need some advice. My permanent coop is 8x8 in square feet and the cieling is high enough for me to stand under with more room still with nest 8 nest boxes, is that big enough? It's made out of wood with a plastic cieling and some windows. The plastic ceiling is secure, but the floor is bare wood (we plan to put down pine shavings), should I put something ontop of it? Can I make any improvements? I plan to keep them on a run because of my dog, letting them out of the coop occasionally when she is inside. Is this a good idea? What size should the run be? Please help, and thank you for your time!
