Hi Guys I have had chickens for a few years now but this one is new to me. Speckled sussex about a year old. She has just been clucky recently. Yesterday I noticed her comb was small and dull. When I threw out some scraps, she didn't go for them. This morning we had to pick her up and drool came out of her mouth. We have isolated her. She is very lethargic. The drool was a new symptom for us. Any clues?
