My laying hens are a few different breeds - Dominiques, SL Wyandottes, Delaware and Americaunas. The rooster we have is a Buff Orpington, and he's just joined the flock a few months ago. Both the rooster and hens are about the same age, just about a year now. The rooster is much bigger than the hens, and they're starting to show some "wear and tear." About half the hens are loosing feathers on their back and neck, and one is losing the feathers on her wings. I know I can put some chicken saddles on them, but that won't help the one with the featherless wings. I'm wondering if the rooster is just too big for the hens and is causing them too much stress and strain. He's a little less than double their size. Thoughts?
