One of our 24 5-day old chicks was found in the brooder dead yesterday afternoon. It was where it usually sleeps and appears normal - no poop on its butt and was active from the start. Is this something that just happens? Like a SIDS type thing every once in a while? We let each of the kids pick out a chick when we were ordering them and this is one of 3 that the kids were calling theirs. She was a buff polish with a cute little top hat that made her stick out from all the other chicks.
