My 1 year old hen has seemed to lost her voice. She seems perfectly fine and I don't think she is sick. She is acting like her normal self. Although her voice seems very raspy. She is normally a noisy chicken and today she isn't really making any noises. When she does, it's a quiet raspy noise. It's pretty hot and humid where I live. I made sure to keep them cool and I made sure they had plenty of water. Does anyone know what it could be? Should I keep her away from my other hen?
