I've noticed my little hen seems to pant a lot, especially at night. When she does this she has her wings held out away from her body. I figured she must be hot, but not sure. The days have been fairly warm but the nights a lot cooler. I've been putting a fan on her too, but she still pants. She is normal otherwise, energetic, eating well. What I'd like to know is, is she just hot, or could something else be wrong, and what can I do for her?
