I lost a chick today, and am not sure about the temp in my brooder, so I'm a little freaked out. I have 2 thermometers in my brooder with 2 heat lamps. One is reading around 84-85 degrees and the other is in the low to mid-90s... meost of the chicks are huddled in 2 bunches on the cooler side of the brooder, while a few are sleeping on the warmer side. Its supposed to get down to 27 degrees here tonight- will they be ok?
