Just need to build a plain coop for my Guineas to be able to stay in this winter. I've got a 6' X 12' chicken coop now. It has a 1000 sq ft run. I closed off a 1/3 of the run to keep the Guineas in. All but one of my Guineas I got as adults. The one thinks he is a chicken and free ranges with them and stays in the chicken coop. From what I've read about Guineas flying off, I may not let the others free range till next Spring. I've built them a roost closed off in the back and one side and a roof. That will keep them dry this Summer. But once it starts getting cold I want a coop they can go into. I will probably use a sheet of plywood for the floor. So it will be 4' X 8'. Anything I should know that I should design the inside different than you would a chicken coop? Guess I'm mainly talking about nesting boxes. But anything else too? Talking about 8 Guineas right now.
