Last winter my beautiful rooster got a bad case of frostbite and lost one tip of his gorgeous comb. I was so sad. I read many places that once a rooster experiences frostbite, he is not susceptible to it again in the future, that somehow the initial episode of frostbite sort of cauterizes the comb off or something, as I understood it. But I'm not sure I believe this. Does anyone know whether it is true? My rooster's comb is looking bad again, and I'm wondering if he's going to have to suffer again this winter. I notice he is shaking his head a lot, just like he did last winter when it got super cold and snowy like it is here now, with increased humidity.
