I recently purchased some Wyandottes and Welsummers. The Welsummer hen has been "hen-pecking" the two Wyandotte hens. I think she has hurt one foot. The hen holds the foot up and I did see blood on her roost. What can I do about the foot? I do not see any cuts, marks, or abrasions on the foot and no evidence of bleeding from the foot. Also, Welsummer hen won't let the Wyandottes feed with her, get water with her, nor scratch in the same area of the yard as her. She is one mean hen! Do I need to get rid of her? I haven't been around chickens since I was very young, and am basically a green-horn. Any help/advice would be greatly appreciated!
