I got three new chicks on Wednesday, one Black Star, one Plymouth Rock, and one EE. They all were doing fine Wed, Thurs, Fri, and Sat. Today the EE started to seem lethargic. She just sits around and sleeps. She doesnt seem to be eating, even when I put here near the food. She doesn't drink when I tip her beak in the water. The other chicks will run around and play, and she just sits there. What could be wrong with her and what can I do to help make her better?? I'm really worried about her.
