I s'pose some of in you would say I should cull my bully chicken. She was a bully last winter too. My SLW is a MEANY, she'll pluck the feathers from the base of others' tails, sometimes eating them, sometimes not. She picks on one particular hen a lot. she ONLY does it in the winter. Why do you think she does this? I want to STOP it before the others catch on...like last year...which took forever to stop...there are some still recovering from last year...murmur, murmur, murmur. I recently switched to higher protein food. I hope that will help.
