So, another update. For the last week and a half, both pearl star leghorns(Cinnamon and Sweet Pea) and the light brahma(Popcorn) have been in the coop together, very successfully. So, yesterday, I introduced back one of the black sex links(Fairy). They were all out free ranging and Fairy just could not leave Popcorn alone. Those butt feathers were just too tempting I guess. Then she was going after Cinnamon. It got dark and I was hoping they would be ok through the night. Well, this morning, while I was eating breakfast, I saw her going after Popcorn and Cinnamon again. So, my husband and I went out and checked. Popcorn has been bloodied again. We have culled Fairy the bully. Broomstick method. Now, Popcorn is back in her dog cage. She doesn't look bad, hoping she heals well. I do still have another black sex link(Midnight) in another dog cage, in chicken jail. She was bullying too. I will wait a few days and put her in with the others. If she still bullies, out she goes too. I will not have that in my flock. And I will never again get black sex link chickens
