I had been testing the brooder for days before the chicks came home to make sure I was between 95 and 97. Thought I was all set. I put the chicks in yesterday and they did the chick huddle for a few hours. I called an audible and lowered the lamp. 5 minutes later they were scurrying all over the place. I took the temp of the brooder last night and it was 110 but they were sleeping throughout the brooder. I got nervous this morning and raised the light a bit abd now have 99 on the thermometer. They are not running around too much. Mostly staying near the light. So which is it? Do I go with the thermometer or visual cues?
