Edit: never mind, you said she DIDN'T have a bad shed.
Make sure you have a way to measure temps, otherwise you will not know if the heat lamp is enough or too much. She should have 80 degree ambient temperature with a 90 degree hot spot. Get an undertank heater ASAP and a thermostat to control it.
Offer food once she is settled in. Or you could wait a week. Some people believe it is of utmost importance to leave the snake alone for 7 days. I prefer to go on a case by case basis.
Regardless of what you do, make sure she has fresh water at all times and has plenty of boxes or containers to hide in within her cage.![]()
