I got 27 chicks in the mail Monday from Murray McMurray. Yesterday, one of the yellow ones I noticed had poop stuck on her so I ran warm water over it until I cleaned it off. Put her back in the brooder and watched until I saw her poop. Feathers fluffed back out and she laid down to sleep, looked exhausted. This morning she was dead. Did I notice too late? Now I'm checking all the others and haven't noticed any with the poopy so hopefully this is the only one. I had no idea they could die so quickly from that.
