We are not sure what going on with this chick. She's about 12 weeks old and is the smallest of our flock. We've got 3 Isa Browns who are about 13-14 weeks old, and 3 Ameracaunas or EEs that are 11-12 weeks old. The EE pictured here is the smallest. The other two are about the size of the Isa Browns. I know it could be pecking but we never see blood, we are always checking. She eats, drinks, acts like a normal chicken. Any guesses? Tricks? Tips on what we can do to help her.
