My little 8wk old buff chick has been lethargic for 3-4 days. I think it was day two I gently felt her crop to see if she had been eating, it was very full but felt like liquid not food. By the evening of the next day her crop was completely empty. She has lost a fair amount of weight and has a poor sense of balance. She is currently by herself and is being good at eating watery chick starter. Yesterday and today she seems to be more active. I've been giving her Nutri-Gel (only thing I have on hand currently) in water and I cannot see any blood in her droppings. None of my other chicks are sick at all, it's just Sunny.
