I'm having a serious pecking problem. They are leghorns, and they have 4 square feet per bird in the coop. They have been free ranging every day except the days when there's a blizzard. I have several chickens injured from pecking, the most severe I separated and put in my only dog crate. The others have large peck wounds on their feet, and I don't have anywhere to separate them to. I've bandaged the feet but the chickens are still pecking at it. Could it be boredom because they don't have much to do outside this time of year? I never thought this would happen with free range chickens. I need a solution. Please help. Any ideas would be appreciated.
