Per my recent update ( https://www.backyardchickens.com/forum/viewtopic.php?id=567922 ), I've successfully (for now, anyway, until hormones kick in, LOL!) introduced the Young 'Uns (16 week old hen Audrey and roo Bianco) to the Oldsters (hens Clarice and Svetlana). They are getting along well out in their 10x20 run area and the Young 'Uns are now going into the coop on their own (after initial confusion of wanting to go back into the Mini Cooper (smaller coop they were using when the 2 pens were separate). BUT they won't roost! They were going up on 1-2 foot high roosts both in their quarantine dog crate and in the Mini Cooper, so they know that's what they should do, but they won't do it in the big coop. There is a slanted ladder, with the bottom roost only a little over a foot off the ground, but every evening when I go in, Clarice and Svet are up at the very top and the Young 'Uns are clustered around the man door waiting for me! I lift them up on the roosts and they stay there happily. But they won't do it on their own! I've tried waiting until my bedtime (10-ish), which is 2+ hours after they've cooped up, and they are STILL clustered around the door chattering and upset. What the heck?? Do I just keep putting them up there? Let them spend a few nights on the floor so they figure it out for themselves? I don't think Clarice, my alpha hen, is stopping them--she leaves them alone once they're up there and seems unconcerned. Help!
