I have ten birds, nine months old.two are male and get along with each other, in fact the smaller one defers to the larger. Several of the females have bare sore patches on their wings and backs. I assume this is where one or both roosters hold on while mating. I put saddle/aprons on them but they ride up when a rooster mounts.I've read advice to cull all roosters but I would like to hatch some eggs and also the head rooster is a good protector. I have begun trimming nails and claws but that is a slow process waiting for the quick to heal and recede. Does having two roosters contribute to the problem by making them more "vigorous?" I am not overly sentimental about the emotional trauma as some people are but I don't want them in pain or unhealthy. Am I missing any solutions?
