Hello
He is bound to be scared and jumpy having just moved to you. It's best not to move their cages at all - any change of environment - even moving the cage to another room - is a major thing for them. I can understand you wanting to let him out if he is hyperactive but just wondering how hyperactive. It is normal for them to go a bit crazy exploring their new cage on the first day, or running in the wheel a bit - a combination of stress and excitement.
But sometimes if something isn't right in the cage they will get stressed. Is the cage big enough? Enough substrate? Can he reach his food and water bottle ok? Is the wheel big enough? Somewhere to hide away (a house or shelf or substrate to bury himself in?) That kind of thing.
He's had a little adventure and is probably scared but he'll get over it
Probably best now to leave him alone for 2 or 3 days to settle in (24 hours isn't really long enough) and talk to him through the bars so he gets familiar with you.
If you have a photo of your cage, can suggest if something may help him settle in easier. How is he at the moment?
