Hi, We are thinking of 10 or 12 guineas. We will provide a coop for night and cold weather protection. They will share a 24 x24 run with 15 pullets. The guineas will be free range during the day so will not have too much time in the run unless we are away. Question Our current coop 4 x 8 is not large enough to accommodate the guineas so we will need to start fresh for them. Do guineas need nest boxes like chickens? I know they will need roosts. What do we need to provide in a guinea coop? We recently lost our flock to raccoons so we are starting again, the keets and chicks will be brooded together. I am really looking forward to the arrival of all those little fluff balls!
