I have 5 hens and one rooster. I had to separate the rooster from then hens because he was over mating them and they are starting to loose feathers on their backsides from it. A couple of them have bald patches. I tried chicken saddles for the bald ones but it hasn't been much help... And they manage to get the saddles off after a couple of weeks. I separated them yesterday. I'm curious if their is something like maybe a supplement I can give them to help promote regrowth. They still have a full bag of layer crumbles for feed. Is there anything I can add to it or just give them that will help with regrowth of feathers? Any advice is much appreciated!
