Hi, I'm new... I've been reading posts on here for at least a year and I always find my answer but now I'm at my wit's end trying to figure out what to do and just need to let it all out and hear what answers and advice come. My rooster and 3 hens grew up together and are all a little over a year old. He has a silkie hen, and his best friend is a barred rock, those two hang out all day together like mates while the silkie hen kind of tags along. The third hen is a New Jersey giant. He has always chased after her since he started mating them. She's missing tons of her back feathers from mating. But now she is also missing lots of feathers from her bum, where I've discovered within the last two months there are also sores, blood blister looking spots, and scabs. I checked for lice and mites. Don't see that. He's pulling her feathers out! People ask me if I'm sure it's not the barred rock but it's definitely the rooster. I've seen him do it many many times. I've even caught him with 3-6 feathers in his mouth! And he's done it right in front of us all in the yard. She hides from him. She puts her face down in a dark corner throughout the day if they are in the coop. At any given moment that I look out the window I will most likely see him pecking her into submission in the same dark corner behind the run's hatch door. He chases her and pecks at her feet or bum or head. But only her! I've separated him for a week, when he returned to the flock he did it again. I separated him for 2 weeks. Upon his return he did it again. He is separated again now and it's been another week. When he is gone she regains her confidence and hangs out with the others, usually peacefully side-by-side with the barred rock. I read that I should put blu-kote on her bum, which I did, and she's healing, but he's not deterred. No one else pecks at her. Now, in addition, in an attempt to give him more hens, we let the the silkie hen raise 6 babies... three of them turned out to be roosters. They are almost three months old. I read that maybe the rooster is plucking her feathers bc he needs more protein so I started growing black soldier fly maggots (blegh... shudder) and feed them to him and all of rest. Doesn't stop him from pulling out her feathers, though. During the day when they free range he chases her but she has room to run. She always runs to us for help if we're outside. And still when he catches up to her he pulls out her feathers. She wanders away from the flock and seems happy to do her own thing. Is this a reason he would bully her and only her, or is she doing it to get some peace and quiet? Bc when he's in solitary, she and the barred rock stick side by side in the coop or free ranging, dust bathing, sun bathing, all of it. I've also read that she is probably the weakest hen, but if I got rid of her then would he likely bully the next weakest hen? She's our most family-friendly hen, she even comes to the door to see where we are. I got the silkies bc I always read that they are the friendliest but it's the jersey giant, hands down, for us that is the friendliest as well as most interactive. I would not like to get rid of her! He seems good to the rest of the flock, although a bit rough when mating. I've seen him call the barred rock over to eat things he's found, I've watched him groom the silkie hen, he guards over them, he never eats before the hens, he alerts everyone at the slightest suspicion of danger, he even sends the whole flock to their coop at night and then goes back to his own bachelor pad, he is getting so used to being in solitary confinement. But as soon as he gets integrated back in the big coop, let the feather plucking begin. but only for the New Jersey giant hen. I'm going crazy trying to figure out if his behavior is unacceptable and if he should be replaced with a new guy? Will having more hens be enough to help if we fill in the flock with some additional hens? Will the young roosters learn this behavior from him if they are around him too long before they are re-homed? I've read that some roosters outgrow rough behavior... Is it rough behavior or straight up bullying? We are leaving this week for a month and the chickens will be in the care of a pet sitter. So now my anxiety level has risen, and I decided I had to find out if I should act before we leave. And what is the general consensus as to how to handle this situation? I've mentioned everything I can think of, hence this very long post- I'm sorry about the length and I'm sorry if I'm asking too many questions in a post but thank you for taking the time to read it. Below is a picture of their coop and the a-frame coop we use when he gets put in solitary, close to the run, so you can see how much space they have, and they range on 1/2 acre. I do believe they have ample space. also, a picture of her bum area, this was about a month ago, her feathers are much more scarce at this point, but she is beginning to heal from him being separated and using the blu-kote. he came into our flock when someone gave me a 'buddy' for the young silkie chick when i got her. i was suspicious but i couldn't tell he was a rooster, so when we finally heard him crow, we had already become attached and decided to keep him around with his 'wife'. ironically, the jersey giant slept with them in a huddle and protected them from the bigger pullets, including the barred rock and a rhode island red we used to have. this is the thanks she gets…:/ If I've left out pertinent information please let me know.
