They can adapt pretty easily. You should just be thankful hes only trying to burrow and get away and not bite you (balls generally arent aggressive but they are out there). I got a 6 year old breeder female around 7 months ago and she tried to kill me everytime I went to pull out her tub. However she has now calmed down alot and I am able to take her out and hold her now, still dont trust her all the way though. Good Luck, you shouldnt have a problem.
