Thanks, many thanks to all who have shared your great ideas and experience for building a coop... I'm almost done building a 4' x 8' coop for my 8 birds, and am designing the roost and droppings boards. Will a 7-and-a-half foot long roost be enough for 8 or 10 birds? I'm thinking about putting the roost about 4' high so the board will be easy to clean, at about 3 1/2 feet high. (the ceiling will be 7 1/2 feet tall inside). Right now all eight biddies are sleeping in an extra-large dog kennel, they happily squeeze themselves in when it gets dark out .... it will feel like a mansion when they get their new home in a couple days!!!
