New here and New to BP husbandry, how long to let her hide.

[Stewart_Reptiles]

How long should I leave her a lone before attempting to handle her again?

The priorities when you get a new animal are

1# Let them settle in
2# Have a successful feeding

I generally recommend new owner to leave the animal alone for a week (No handling) and offer food at the end of that week than if successful you will be to handle your new BP 48 hours later, if not successful wait another week offer food again (same still no handling)

Is it possible she could stay in there long enough to put herself at risk of poor health, e.g. not eating enough, not having access to water?

Nope she is fine, remember that is what they do, BP spend about 80% of their time hiding whether it is in captivity or in the wild.

When I want to handle one of mine I just lift up the hide (if there is an hide in the enclosure) make the animal aware of my presence and than pick it up.
