I went down into the basement this morning to find a dead chick in the brooder. It was a week old. I hatch my own chicks every year and never had one die a week after hatching. She seemed healthy last night running around. I'm hoping she was just weak and it is not some sickness that will go thru the rest of my chicks. I will keep a sharp eye on the rest for anything unusual . I use the Premier heat plate and she was 1/2 under and 1/2 out when I found her. It figures it was the only one I had named because she was pure black. RIP Coal.
