This is our 1st winter with chickens...we live in MN and this has been out 1st truly cold week. Mr. Ballchinion (our rooster) got his waddles & comb frostbit the beginning of the week. All of our chickens have since been confined to their room in the barn! He also looks like he might be molting & a couple of our hens are also loosing some feathers by their tails. 1. How do I treat his frostbite? 2. Is his feather loss related to his frostbite or is he molting? 3. Are my hens starting to molt, or is it due to a bored bully chicken pecking on them?
