Lots of variables here.
Age at release time.
What they have been fed while captive.
Type of water system they are used to.

BIG --- How isolated from man have they been kept , so they keep some of their Will instincts.
The more you are around Bob Whites the tamer they get ,and the easier it it for a predator to get them.
