I'm wondering if Pearl, my molting chicken isn't sick, but being picked on. We only have 3, but Rose is the boss. I notice some pin feathers have been removed from Pearls neck. Do chickens fight? I've always considered us lucky that the boss has only given the occasional peck to the underling, usually around food, but could it have escalated? I'm thinking of separating them at night, but I honestly want to separate the mean one and let Pearl be with her "neutral" sister on the roost at night. Anyone separated the dominate chicken and let the lesser one stay with the group?
