One of our hens escaped from the coop and got frostbite on her comb. Being the newbies we are, we brought her inside to treat the frostbite and had her inside for about a week, so we are reintroducing her to the flock now. We isolated her with one other hen so she would have an ally when she goes back to the coop and we're letting them work out their pecking order. How long will that take? We were hoping to put them both back in the coop after about 2 days, should that be long enough?
