My poor little girls. I have 3 RIRs who are about 25 weeks old. I've been putting vaseline on them every night but it doesn't seem to be helping. I didn't even bother tonight because it's such a hassle trying to get it on them. I'm trying to create more ventilation in their coop. I live in Oklahoma though so it's always a little bit humid no matter the temperature. They are all acting fine, eating and drinking as they should. We got 2 eggs today even. All 3 have black on their combs and wattles. It just looks painful even though it doesn't seem to be bothering them. I'll try to get a picture tomorrow. It's dark already. It's only 5:30 but it the temp is 31 feels like 23. 30% humidity. What can I do?
