It is not unusual for a young BP to be what some would refer to as being nippy, they really are only being defensive and do so for various reasons
1# They see you as threat in their eyes you are a predator.
2# Younger BP might need a little time to adjust to their new surrounding, husbandry, and routine.
Prior to handle your new snake make sure to observe his body language; if your snake is in a striking position do not attempt to handle it.
Always make your snake aware of your presence prior to handling.
Make sure your husbandry is optimum (security being very important) , establish a good feeding routine, feed your new BP in his enclosure and not outside, do not over handle, and most importantly be patient.
Not being handled by the breeder has nothing to do with it
