I have a 3 year old gold sex link hen. She stopped laying about 3 weeks ago. She stopped eating her chicken food 2 weeks ago. Was eating fresh veggies and fruit and drinking well until this morning, now will not eat or drink at all. Comb is dry and has fallen over. Very thin. Never has had raspy breath. No sour smell from crop. Will not stand up this morning. Treated for Cocci 2 weeks ago with Fort Dodge additive to water, treated whole flock (5 total) for 5 days. She would fill her crop with fresh food....but not chicken food for last 2 weeks. I feel so bad for her. Would have posted sooner but she had been eating, drinking and not getting picked on by other 4 chickens.
