I have a 1 1/2 year old buff orpington. The last 2 days has been very lethargic. Closing eyes, and keeping to her self. Yesterday I got her to eat some scrambled eggs, and drink water. Today, her crop is empty, she only picks a little bit at eggs. Have no idea when she laid an egg last. She lost a lot of feathers about 2 months ago, and has never regrown them. I have seen her in the nest box, She can not stand she is so weak. She is NOT coughing, sneezing, nothing respitory. I'm afraid I'm going to lose her. Help me.
