I have 2 red sex link chicks and 2 poults in a brooder in my garage. Here's my question: daily temperatures here are now between 90 and 100 degrees, but it gets cool at night (then I turn on the heat lamp)...later this week it's going to get up to 105. Is that too warm for the babies? Is it ok what I'm doing, turning off the lamp when it gets over 90 degrees? Or would it be better to more precisely control the temperature to keep it at a constant 95 or so? Thanks!
