Thank you! I am going to add another light, they will still have room to get out of heat, but I am worried they are overcrowding the heated area, it is staying right on the upside of 90 degrees
For the first bit 90 degrees is perfect. They say you can go down ten degrees for each week. I usually leave it around 90 for the first week and then drop it down to 80 or so for the few weeks after that. With enough space that they can get out of the heat like you said if they get too hot
