My little Feather, seen in this post https://www.backyardchickens.com/t/699313/feather-the-odd-cochin , is not feeling well. She has been this way since Friday and I am really worried. She is somewhere around 15 weeks old. She is lethargic, and her eyes are closed almost always. Before I isolated her she stood in the corner of the chicken run with her eyes closed, and I know she wasn't sleeping. Sometimes when her eyes are closed she will peck around in the air, as if she is eating imaginary floating food. I at first though sour crop, so I treated for that, but she didn't get better. Her crop isn't ruptured because when she eats and drinks, her crop holds the food. I have checked her droppings for worms under the microscope, and there weren't any. Because of her age, she can't be eggbound. Or can she? So here's the question: What IS wrong with my Feather?
