OK so I was reading one of tom's threads about humidity for babies, he said that there should be a humid hide, warm soaks, and the whole enclosure should be fairly humid. So I started spraying down the enclosure once a day and giving them warm bathes every other day(I'd like to add a humid hide soon). They loved it for about two weeks... then I added a CHE to keep it warmer during the night(It was getting way to cold at night and one of the got a runny nose. He is better now tho) and about a week later they all started getting very lethargic and sluggish. Why?
