Hello. So this morning my Rooster has got a little frostbite. Feel so sad now, I really dont want to him have all life that ugly blue, violet colouring in comb.. First pretty cold night, but I have few ventilations to prevent big moisture, but that as looks make the night under -0 celsium. Just read about that in this forum.. btw, one is from ground, as I just read somewhere there is good overhead ventilation not ground, but noone was write that, just ventilation... If the comb is now blue/violet can it can turn red or that it is? For all life? Can I put som iodim or smth to just do smth better than no? Thanks.
