Answer
There are a couple of possibilities. First, they could be playing. Second, if one is a male and one a female, they could be courting or mating. Third, one bird might be more aggressive than the other and they are just trying to figure out who is in charge. That's especially true because you have only had the birds a short time. They are both stressed from the move and your put them together before they were even adjusted to their new home. As long as they are not hurting each other, you don't have to do anything. If they are or you are worried about them, put them in separate cages for a couple of months but put the cages next to each other. Good luck. Also, get yourself a book on budgies if you haven't already. It will be helpful. Good luck
