ok, you need to make the hot side warmer. It should be 88-92 degrees. (if it isn't warm enough BP's won't eat. This might be part of your problem)
What do you have as far as hides go?
You should get on of these, they cost $12 at Walmart and measure 2 temperatures (hot side and cool side) and humidity all in one unit.
What is the cool side temperature by the way?
I suggest you give this a read, it should help.
