Hi all, we have an acre run with about 35 to 50 hens and 3 roosters. About 10 to 15 of our hens are losing feathers on their backs, and tops of their heads. I am 99% sure it is our 3 roosters despite there being 10 to 15 birds per roo. The run has plenty of grass, brush and trees for the hens to escape the roosters, but the hens just keep happily submitting. A few hens now are completely bald on their backs, yet they dont seem to mind. Before I go through the brute force method of making 10 to 15 saddles for the hens, are there any other suggestions?
