Hi Erik,

Its best to put them back in there enclosures right after they eat and leave them alone for at least 8-12hours, best even a whole day. They need time to get the food down a little before they get active again.
And she is probably verry stressed caused by the fall from the top screen and is hiding till she feels secure again.
As long as she didn't regurge her meal after the drop, i think she will be ok.
