I have an 18-month old Australorp hen who has stopped laying and started molting (with a vengeance - primary flight feathers everywhere). I noticed today that her comb and wattles are fading to a sort of pinkish-grey. Not in spots or lesions like fowl pox, just a general fading of color. Her sister, who has continued to lay and has not started molting, does not exhibit this fading (part of why I noticed). I'm hoping that it's no big deal, but I'm hpoing someone has some input to offer. I'm prepared to isolate her if neccessary, but since I've got 5 hens in a single tractor, I can't think that, if it were something infection, that they'd all have it.
