This may seem like a bit of a silly question, but when testing the temp in the brooder, is it best to put the thermometer directly under the lamp, or elsewhere? I have a large cardboard box for a brooder with an open top. I am in the South where it's quite warm. The temp directly under the light is over 100 degrees. Is this ok as long as the chicks have plenty of room to move away from the heat? Please let me know what you think. (By the way, it is already in the mid 70s here).
