Temperatures here in Idaho have dropped 30 degrees in the last day or so. The high for today was forecast to be 38 with 25 mph winds. Brrrr. My 10 day old chicks are in a shed with a space heater and in a commercial brooder. It's a tin box thing about 2 feet by 3 feet. I found them today standing under the heat element. Yesterday they were doing all kinds of stuff: jumping off the feeder and flapping their wings, pecking, and wandering around and peeping happily. So obviously they are cold. I put a blanket over the brooder leaving the end open so they could get air and added a heatlamp above the brooder to warm things up. My questions is how to tell how cold they are. I thought when they got cold, they did their upset cheeping noise. These guys were not making any noise at all. So are they okay, a little chilly. gee it is nice here by the heat? Or are they mostly frozen, too cold to make a sound, about to die cold? They were mostly standing under the heat element with a little space between them, not moving or doing anything at all. I'm just a little freeked out is all. I don't know whether to take emergency measures or relax and go to bed.
