Hello, I’m new to raising chickens and have 6 hens and 1 roo. With this said today I noticed the hens who are 20 weeks have what looks like dry skin or white on their combs. They are still not fully mature and one hen is finally laying…. I’ve been reaserching and have seen so many things so hoping this community can help. I’m in WA and the weather is rainy and getting a lot cooler at night so not sure if it’s just dry?
