I just had a guy stop by and pick up my two roo's. He looked at my silkie hens and said they have mange? I never noticed, until he pointed it out. I'll try to explain it as best as I can, but please be patient as I'm new to all this (I know pictures would help, but my camera isn't working). So say your looking at just one feather, well that feather looks like it's had a razor taken to it and just shredded it. If that makes any sense... It's like that on about half of their wing feathers. My Orps haven't gotten it yet. But the guy said it would spread if I didn't do anything about it. He said what he does with his birds is take them inside and put hot water on their feathers and then let them dry out inside for a few days? I trust him to a certian extent. He also told me hen's don't lay without roosters... so you see my perdictament! Lol. Any help will be greatly appreciated. I've looked online for mange in chickens without much luck. Thanks!
