We have a chicken that has a blister on her comb from frostbite. We live in Northwest Indiana and, despite our best efforts, the super cold got her. How do we treat this? After doing some searching online we are still confused about what we should do. Should we bring her inside? Should we put something on it? Will she need a vet visit? Or an antibiotic? She is acting fine otherwise. Any advice you can give would be greatly appreciated!
