We do not get cold here so I do not have experience with heating coops, water fountains and etc.How often will you do this electrolyte supplementation before the polar vortex arrives? Every day?
Related thought... Friend with chickens says he uses an infrared lizard light (whatever that is) to warm the coop in the ultra frigid temps. Does anyone use something like that? Is a low of 0 F cold enough to warrant some heat in the coop, or not? I'm confident of enough ventilation, and I don't put any water in the coop.
My cockerel has some frostbite on his long floppily doppily wattles, and maybe a bit on a point or two on his comb. The girls' combs and wattles are all fine.
