Can you describe the enclosure in detail? A description helps (See the “trouble in the enclosure” sticky).

Nonetheless, a few suggestions come to mind. Most importantly I’d advise you to avoid handling. Handling can stress your frog very easily. Also I would give your froglet time to acclimate. What size and type of prey are you offering? When are you offering it? (I.e after lights out?) Some frogs can be finicky.
