We had a rooster problem so we cut our rooster population to only 1. He is still quite worked up and being more agressive than we'd like him to be. Every morning when i let them out into the run he spends about 5 minutes running around the run and being agressive. This morning for instance he ran around beating on the hens over and over. My son was in tears from his behavior which was worse today than some days. The rooster is grabbing the hens by the heads and/or combs, he's running them right into the fence, he's chasing them through the feed dishes and into the coop, etc. He never used to be this agressive, just his usual plucky dance and breed the hens. Now the hens run from him and those who can't escape just sit there afterwards for a while seaming to recover from their ordeal. We also have 3 hens who've started fighting with each other, though 2 are the worst. When i say fighting i mean neck feathers up, in fighting position, just like a cock fight. They fly up in the air, they kick each other, they hold each other down by the neck feathers, they chase each other around the pen. I am TOTALLY sure they are hens, but if i didn't know that i'd swear it was a full on cock fight! These hens have a lot of feather damage, too. They just randomly (to me anyhow) attack one another throughout the day but like the rooster it seams to be worse in the mornings. I have taken very good care of these birds. They have more room and better feed than any batch i've previously had. But i've never had so many behavior problems, feather plucking/bare spots, ever before. I don't know why this is happening or if it's just the breed is more prone to these behavior's? The hens that are problematic are all Golden Comets (i know they're a hybrid and not a true breed) and i've never had them before, but i'll never get them again either. I'll never have another rooster either after this adventure. Anyhow, does anyone have any ideas of what the problem might be here? If we get rid of the rooster do you think the hens will simmer down? The rooster has gotten very agressive with people now too-i'm the last human he'll allow in the run during daylight and then only if he feels like letting me in. He wasn't like this when the other rooster was still in there. If it matters at all they've got an 8'x8' coop attached to an 12'x12' run (free-range is not an option here). I feed them Purina Omega-3 feed in 4 different locations, with veggies, fruits, and other chicken friendly snacks mixed in in the mornings and they get picked grass most afternoons. Thanks for the help! We're out of ideas of what to do other than get rid of them all and start over with heritage breed hens only as i've never had any problems like this with them.
