Something drug my hand off and plotter clean of her belly feathers and hind back feathers but she somehow managed to escape and showed back up the next morning. She doesn't have any major wounds but I'm concerned about her being in the cold without any feathers on her belly. Can she make it in the coop without a heating source? We live in Texas so the nights get down into the 40s and daytime is currently in the high 50s. She's about 2 years old.
