New female hates being handled

Sarahkate11 you wrote in the 1st post on this thread that you're "so used to our other guy who is a love and loves exploring outside his enclosure." So what is it that makes you confident around that one as opposed to this one?

You only got it a week ago. Leave it alone for a week then try feeding. If you get 3 successful feeds in a row, then you can start to handle. It's like 4 weeks of not handling, but best for the snake.

Time to settle into a new enclosure will prove helpful along with the regular feedings. They all have their own temperaments and most only tolerate handling and are not big fans of it.

Like everyone else said, give the snake some time to settle in, a week or two. After that time, if she is still aggressive towards you, have girlfriend hold her while you pet her, or maybe hold half of her body. That way if you get scared your girlfriend can take over. I believe snakes can tell when you're nervous, so if you portray confidence and start small by just petting her, this will help you gain confidence and learn how to feel safe.

When I first got my ball python Twister, he hissed every time I would go to pick him up. He never lunged like your girl, but it was still intimidating. It scared me a bit at first, but I learned that if I just picked him right up he didn't do anything, he's all bark and no bite lol.
