I was given an old coop from a friend. It is a big coop he had over 30 chickens in it when he used it. I fixed it up made it nice and the chickens love it. I have 10 chickens in it. I just got my first couple eggs this week so I put the nesting boxes in with fake eggs to show them where to lay. The issue is all the birds including the rooster just crowd in the nesting box area. No one using the roosting bars. Is there anything I can do to fix this?
