Whooo, where to begin...... I'm going to try not to sound like an arse here but you've GOT to make a few changes.....

#1 They should DEFINITELY be in separate enclosures! The female sounds like she is still WAY too small to be laying eggs. If she were to have them she would most likely become egg-bound which can be FATAL! The "cuddling" and "snuggling" they are doing is actually them vying for dominance which can be extremely stressful for the snake.

#2 Temperatures and humidity. 50% humidity is what you should be shooting for, any higher than that and you are putting them both at risk for a respiratory infection (another reason you should keep them seperate, if one gets sick the other one will too RIs are viral!). You do NOT need to have a nighttime drop in temperatures. Temps should be approximately 92 degrees on the warm side and 80-83 on the cool side 24 hours a day. Lamps are unneccesary and actually do more to stress the snakes than anything. They do not require UVA or UVB light (despite what the pet store people will tell you to try and sell a $20 light bulb). The best thing to heat the tank is an undertank heater CONTROLLED with a thermostat.

#3 are you prepared with an incubator in case the female does lay eggs? It takes a fairly specialized incubator to properly hatch ball python eggs. The temperature and humidity MUST be closely monitored or your eggs will go bad extremely fast.

Sorry if I come across wrong I just want to see your snakes get the best care they possibly can.
BTW Have you considered getting a couple of actual snake cages? Reptile Basics makes some great ones, they come with heat installed and a light if you should choose to view them. www.reptilebasics.com you can ask Rich (the owner) anything you'd like and he's very quick to respond to questions and their product is AMAZING!

Good Luck!
