I've got 24 one week old Cornish X in my 50 gallon water trough brooder. The brooder is in the tack room of my horse barn. (yes, I posted that I was considering brooding them In the garage this time, but I wimped out!). While the tack room is not climate controlled per se, it is insulated, so it actually stays at a reasonable temperature in the summer with the window open. I'd guess it is about 75 degrees. The past couple days have been unseasonably hot, so I've been checking the temperature in the brooder every couple hours. I've actually turned the brooder light off for several hours the past two days. Today was much cooler. Although the temperature in the brooder was only in the 80s, the chicks seemed to prefer napping on the end away from the light. One was panting, although everyone else seemed cool enough. Should I even bother having the light on anymore? I don't want them to get a chill, especially since they like to lie in the water they spill out of their waterers. On the other hand, I know these freakizoids overheat easily; and they seem plenty warm even at a temperature 10 degrees lower than recommended for chicks their age. Next couple days are to be in the 80s or 90s. Can I just can the brooder light?
