I've already separated the roosters in different pens. They grew up together. When I observed their behaviors for a week while free ranging something weird happened. The 24 week old barred rock rooster would sneak up behind the 24 week old white/brown mix rooster and grab his feathers until they are pulled out then chase him all over the yard. Then he would eat them. I thought this might be a one time deal but he did it again today. Why are earth would a rooster eat the feathers? Maybe he tasted blood? My barred rock rooster will chase the white/brown rooster and the 16 week old hens until he pulls out feathers. I know roosters will try to be the dominant one of a flock by fighting but eating feathers? I had to separate them b/c the mix rooster is a gentleman to all of the hens and he would come up to anyone for a treat. A trait I like to keep, for breeding in the spring. Any info is very appreciated, thank you.
