One of them decided to molt in the cold weather. She is clearly cold, she is shivering. Her feathers are coming in and she has feathers but she is cold. You can feel it when you hold her. We tried to put a sweater on her, I didn't want to but I also don't want to lose her to being so cold. That didn't work, she kept getting her feet caught in it plus she wouldn't walk in it much and acted like she had no balance either. We can't and don't want to heat the coop. Any suggestions to helping her so she doesn't get sick. We have another night or two before it starts get above freezing but then we realize that this is just the beginning of winter so not sure how cold it will be. WE typically have fairly milld winters as usually in the 40's and 30's during the day. Just seeing if there is anything else I can do to help her. She isn't sick but she is small but she is eating. We give her scratch grains right before bed (all of them). Any ideas?
