What is the best treatment for this? My cockerel has it quite badly, (he came with it) and I can see that now he has infected my hens. He had a spot on product from the vet, but the legs haven't improved. I'm going to take him back to the vet, as he also has a partially bald hear due to one of the hens pulling his "hair" out. But wondered what the most effective and least stressful treatment is. Hopefully something that is safe for egg layers as I need to treat the hens too.
