I have 3 Marans "teens" (7-1/2 weeks) that I would like to move in with The Girls, who are now 3 months old. I have them in a small coop inside my large coop so everyone can get acquainted. How long do I need to keep them in this configuration before I can turn the 3 younger birds out with the older girls? Two of the young birds are roos. And what are your recommendations for doing it -- supervised only, at night when they're roosting, ??? I have some chicks in the brooder that need to move into a larger space, so I thought I'd put them in the small coop as soon as it's available. Thanks for your help!!!
