I’d do a dog crate or a separate area in the coop/run sectioned off with HC, you don’t ever want to integrate a lone hen. So we don’t want her to be completely seperate.
While true, just because they’re young and hormonal with no older birds to keep them in check, doesn’t mean they won’t grow up to be awesome roosters. This hump is often difficult especially with multiple boys with no older birds.
I did nothing. It helped a lot when I got rid of all but one, since it wasn't such a competition for dominance. If I wanted to keep them all I would separate them completely from the females. Out of sight.
