Hey all, We've got 14 barred rock hens at our place and one Silver Laced Wyandotte Rooster in the mix. Our birds free range around 3 acres of pasture most of the day and come back to the coop at night. Well for some reason one of our hens has been ostracized from the flock and whenever the rooster sees her he viciously attacks her. A few weeks ago I started letting her in the barn to roost because she had been bloodied by the roo. This isn't a mating dance, the roo's out for blood. I'm not sure why though, he's pretty docile around me and he's only a little rough mating the other hens. I also have to add that during the early spring I had a hen get sick and we isolated her in a horse stall and tried our best to get her better. A week or two into the recovery the bullied hen started to fly over and hang out with the sick chicken. I don't think that she was getting picked on at this time, she just took an interest in the horse pen. But, the bullying started after we moved the birds outside. Is there any reason that a rooster would come charging across the yard and viciously attack a hen anytime he sees her?
