This is my 7 month old Easter Egger. She doesn't seem sick, her poop looks fine, she's eating ok but I don't think this is right. Both sides look this way. I don't believe the other chickens have been pecking her because it's the same on both sides and none of my other 9 hens are showing signs of being pecked. Any clues as to what's wrong and how I can fix it would be much appreciated. Thanks!
