Jaundice comb on cockerels

[familyfarmer4]

The part that has me the most confused about what it can be is that it’s only the 3 cockerels. None of my other 30 something chickens show any of the same signs. We haven’t experienced a true Midwest winter yet, so I don’t think cold is a factor.

Do the cockerels sleep in a different part of the coop? Could they have gotten wet and come inside for the night in freezing weather? There probably isn’t much to do except watch the combs for any color change. I still have doubts that it is frostbite, but it can change colors. Usually it is on the tips or outer edges. I really hope it is nothing, and just something to do with being winter. Do you see any bright yellow skin on them? Sometimes with liver disease, chicken can look glowing yellow. As long as they are active, and eating well, they are probably okay.
