I went out to feed this morning and noticed one of my chicks (about 8 weeks, being raised by Mama Hen) was just laying near the feeder. Her brother came up and stepped on her and she stood up on one leg and hobbled away, pushing her left leg out in front of her. She can move her toes, and uses them to pinch the dirt to help manauver. Is her leg broken? What is wrong? I'll post pics in a minute.
