So I'm doing chicks on water bottles this year, which I think should be no problem since it's been hot enough to just leave them with nothing lately If anything I'm going to have trouble keeping them from overheating. Never experienced a summer like this. Anyway, despite the fact that I'm confident that I can keep the heat up to where it needs to be, I'm curious. What really*are* the consequences of a chick that's below temp? Now I'm not talking a day-old chick at 40 degrees; I'm talking 10 to 20 degrees under recommended temps. I know that crowding and crushing is the big one. But are there other consequences?
