We are planning on building a new chicken coop for our 26 chickens (they don't free range). This summer, or next summer, I am hoping to get some guinea eggs and have one of the broody's hatch them... but my question is.. Do Guineas need a coop? We are in WI, and I plan to let them free range (we are on 10 acres). Should I make a roosting area above the coop? Like, in the rafters? Or would they be ok in the coop for the night with the chickens? I should I just let them free range at night, too? Pictures of what you do would be really helpful!
