I've had chicken less than a year. This girl was one of my first chicks. She is the roosters favorite. I noticed today her comb, wattle, and face have changed quite a bit. She's been missing back feathers for months. She lays every other day and her eggs are good and hard. I currently have her separated just in case something else is up with her. Can anyone tell me if this is normal molt behavior or should I be looking for something more serious? I've had a saddle on her which I just took off.
