I've never had anything like this happen with my keets before so this was definately a first. I had a batch hatch out maybe 2 weeks ago. Anyways I gathered them up like I always do. I think it was like 15 or so. I missed one that stayed with the hen. Within I'd say 2 days they were all dead but one! At first I thought maybe they were smothering each other? Then I thought are they that stupid that they aren't eating? Like maybe they didn't know how? So I put one of my older RIR chicks in the brooder with the lone survivor and sure enough it lived? The one that stayed with then hen did to. Although I confiscated that one also. So with my second batch of...I think 19 I have left they all are eating fine and think that the RIR is thier momma I think. What the heck?
