I have 38 17 week old RIRs. I lost one Sunday Am and one yesterday AM. Today all were alive YEAH but ..... The 2 that diead looked perfectly normal. They did not show any signs of distress or that they had been pecked or anything like that. Thay are in a portable coop (10 ft by 12 ft)that gets moved everyday to fresh grass. I have not noticed any irregular poops. When I go to check on them they seem happy and healthy so the 2 deaths were confusing. However, this morning I stayed and watched awhile and noticed that some of the chicks have glistening beaks in the morning sun. It looks like thay may have runny noses?? I think I heard one sneeze also while I was out with them. Could this be why they died? We have only had them 1 week and 3 days. Could it just be stress from acclimating? So what do you guys think? I appreciate your help because it sounds like you know alot more than I do! But I have to confess this is not such a fun way to start with chickens. We really have gotten attached to little birdies already.
