I have a young Buff Orpington hen that has black spots on her comb since Tuesday. It has been very mild here in NY but its been in the 20's the last few days. Could it be frostbite or something else? No one else in the flock has this. I have pics, but Im not sure how to post them on here. If someone can tell me how, I will put them up. I want to help her if there's something I need to do!!
