So like 3 days a go, I was feeding my hen and i saw her comb have 1 bit of black. I know is frostbite because when an animal/human outer skin gets hypothermia or gets really cold, the skin turns black. So I took a picture today on her and is snowing today. So anything i can do to help her? Should i buy a coop or build a coop? Should i buy a heat lamp?(I am going to buy that) So stay in my yard underneath a ledge up in my roof. The food and water is underneath it too.
