As a new chicken owner, I am suffering my first loss tonight. My baby "runt-o-the- litter" just didn't make it. She would be three weeks tomorrow. Ever since I've had my 5 Doms, this tiny chick has been ostracized by the other 4. They never did appear to accept her. She always ate alone and slept alone. Is this common chick behavior? Could this contribute to her passing?
