I finished my coop today and am ready to move Rufus and Oreo who are 5 weeks old into the coop. But I have a question about the 3 buff orps and 3 Ameraucaunas that are 3 weeks old. Are they ready to be moved into the coop? The Ameraucaunas have a lot of feathers but the buff orps are still getting them in. Can they be moved into the coop? Thanks
