A broody hen hatched these chicks and is raising them. She seems to be a bit of an aggressive eater and tends to kick the chicks in her scratching. The chicks are about 2 weeks old, and are looking worse and worse. I don't know if they're injured from her kicking or if they have a disease like fowl pox. They act completely normal and have no symptoms that I've noticed. They're fluffy because it's cold out today.
