I have a hen named Sweet. She is under a year old and got a bad peak wound on top of her head. The hen who caused it we are trying to integrate back in the flock after see had healed from a tear on her side. We stuck Sweet in the other hen so she could dry and clean the mud of herself and for some reason the other hen snapped. The injury happen within the past 24 hours because Sweet was placed with the other hen last night and I just checked on them(my sister usually checks the chickens in the morning and I guess she didn't notice) and found the injury. The top of her head is partly torn away and her head is swollen and red. I will be posting pictures after dinner(my dad told me to wait until then) and we will put honey and vetericyn on the wound and the hen that caused the injury has been removed from the cage.
