Now, I thought we did an excellent job - our guineas were going to live here and we'd close the doors each night after they came home. The chickens/ducks live in another house further away with a completely enclosed pen (see my avatar). HOWEVER, once the guineas were old enough to be let out, they decided they did NOT want to live in their own house, they wanted to live with the chickens! So now our guinea hen house is a brooder for keets, chicks and ducklings.
