When I built my rack it didnt have any heat (In a heated room). Well I finaly got my heat tape and set it for 85 days and 80 nights. The room was only sitting about 70 thats why I installed it while trying to breed. Now that I have it a bit warmer Ive noticed that some of my females are sitting on the hot side while some are sitting on the cold side. Should I be worried about the femalse that arnt seeking the cold?
