I am a first timer with baby chicks. Mine were hatched on Wednesday and I got them in the mail on Friday. They seemed to be doing awesome. Very energetic on Friday and Saturday. I cleaned a few pasty butts and added some oatmeal to there feed that I ground up in a clean coffee mill on Saturday night. Sunday morning I woke up and one was dead. Is this just something that happens or should I change something I'm doing? Any advice would be appreciated!
