Went out to check the coop on Christmas day and found a little fuzzy butt just taking a stroll around the nest box.with her mama watching and following close behind. We are having 18*cold weather and about 40 in the afternoon what do I do to keep her warm should Her and mama go to a seperate cage inside the coop? as Idid before but then had a lot of trouble re-intruducing them.in to the flock. I have a 125 white heat lamp and she has been eating. I didnt expect her so have no starterfeed, I am feeding her hard boiled eggs.I dont want to buy a whole bag of starter for one chick. what else can I feed her. she was a nice surprise, Mama had her hidden. any advice?
