I have a hen who got major frostbite and lost all of her toes except for her thumbs (or back toes, whatever they're called) and half a toe on one foot. I was hoping that once all of her frostbite fell off she'd start integrating back into the flock and the bullying would die down. But that's not happening. I have a few other hens that will actively run toward her and attack her until she runs into the chicken coop, just to get away. Is there any way at all to get the bullies to calm down?
