You can uncover screen or add holes as need to maintain proper humidity.

All animals need ventilation and fresh air to be healthy! Do NOT completely cover the screen, it will cause more problems than not - mold, resperatory issues, the works. I may be new to ball pythons, but I most definitely am not new to animals.
