First of all, forgive me if this has been asked and answered. I've searched until I can search no more. One of our girls (a spectacular laying RIR) had a peach colored comb and wattle (2d time we have seen this on her). Within minutes it returns to its normal pretty red color. It really upsets my children because they know frostbite can happen. Sooo..is she okay, what's going on? She is healthy, no mites, laying good, seems happy, etc. Should we be worried?
