Hi! Longtime lurker and first post here. I suppose I should start by thanking BYC for all the tips I've scored from this site already. :)
We have a flock of nine five-month-olds: eight hens (mixed breeds) and one Black Cochin rooster. We first heard our roo crowing a couple weeks ago, and shortly thereafter he quit going up with the ladies to sleep in the coop. There's plenty of room up there, and he never had a problem with it until recently.
I normally let my flock free range through the backyard when I get home from work for a couple hours before dusk. Once he gets the ladies up, he parks himself just inside the run on the ground near the door. When I come out to close it, he bristles at me and gets a bit upset (at first I was manually moving him into the coop, but he's becoming increasingly more intimidating and I don't really care to bicker with him in the dark.)
Do I have to shut him up in the coop again to retrain him? Do I have to make the girls hang out there too if I do? At the moment, it's warm, but winter is not far off and I'd rather see him safe and dry upstairs!
