I recently bought a EE from a friend and when I got her home, I noticed that she had a really bad odor to her. I suppose if I were to describe it, it would be like decay. She's only 1 1/2 yrs old and has a few missing feathers, but no bald spots. She's seems ok otherwise. She stays in the coop and run when I let the others out to free range, but I'm assuming it's because she's new and not ready to explore yet. What could this smell be?? None of my other chicks smell like this.
