My 1.5 yr old white Rock, Martha USED to be at the top of the pecking order but some recent losses to predation and the maturation of our, um...rather amorous rooster, have changed Martha's relative position in the rankings. Last week I noticed feather loss on the back of her head from the rooster and today I saw some blood on her feathers, so I took her into the house and what I found was ghastly. I could actually see her neck bone in one spot. My guess is that the other hens must have been pecking at her. I can't believe hens can be so barbaric. My main question is: What should I do to the injuries beyond having cleaned them? Out of curiosity, why are some spots in the injured area green? Thanks in advance for your informed opinions.
