My brother bought some chicks from Tractor Supply. Day two, one of them (a buff Plymouth Rock) won’t eat. Day one, all were eating and drinking. Day two, I came out in the morning and lifted up the brooder heating plate to check on them. One doesn’t move. I moved it to the waterer, and it drinks for quite a while. But it doesn’t eat, and I haven’t seen it drink again. It barely moves. It can walk. I saw it run over to the brooder heating plate this evening before I left.
