I ordered 12 chicks from Ideal about 2 weeks ago, they sent me 24 altogether. So I had 2 brooders up and running in my house. 2x the brooder making 2x the mess, the dust was killing me. So they had to go outside to the big kid hutch. Our high yesterday was 46° the low 30°. I worried about them all night long. When I checked on them this morning, they were all running around, happy as can be doing little chick things. The thermometer under the heat lamps read 87° the one one the opposite side of the brooder read 35° and they were all eating, drinking and flapping around like a bunch of crazies, not huddled under the light like I expected. Guess that just goes to show they're alot tougher then we give them credit for
