About a week ago I finally got rid of a rooster that had been injuring the hens for months. Their rumps and the backs of their heads were bald and raw from his constant attention. Despite all the injuries, I never had any problem with cannibalism. The roo was very domineering, and I expected that there would be some fighting until a new pecking order was established, but nothing like this. A few days ago I walked in on really nasty fight between two of the larger hens. They were biting each other's combs and clawing at each other, but neither appeared to be seriously hurt and I left them alone to work it out. When I got home later that day the largest hen was missing. I found her out in the pasture, dead, with all of the flesh picked off of her head and neck, and no other injuries. What a gory sight! I'm almost certain that she was killed by the other hens- I've never seen injuries like that from any other predator. I am guessing that she was injured during a fight and the others attacked her because of the wound. So far, none of the others have been pecked, not even those that still have healing sores from the rooster. They are free range during the day, have plenty of indoor space, eat a commercial layer feed supplemented with oyster shell and whatever they eat outside, plenty of nest boxes... Should I be doing anything else to prevent another incident like this one? I never want to see anything like that again!
