I see I'm not alone in this area. Anyway, I have two (of 17) 2 year old hens, red "blank" link, who started getting lethargic then would keep one or both eyes closed. Now they are turning their heads back into their shoulders and just sitting there. Had one 3 weeks back that was doing the same thing and it died about a week after sypmtoms appeared. There was a little bit of "coughing" as much as a chicken can cough in the last one, but haven't noticed that yet with these two. Stools seem normal (although it's hard to tell with 17 of them), eyes don't seem bright when they are open, no other obvious signs of illness. No recent changes to their food or habitat. I live in east central Iowa if that helps. Anyway, if anyone has any ideas it would be greatly appreciated! Thanks, Kent.
