How did your budgie manage to escape?
I truly hope you will be able to get him back.
People have recovered budgies after several days and sometimes even several weeks when someone finds them and turns them in. I would not suggest getting another bird at this point in time. And, if you to get another budgie at a future date, please don't forget that you'll need to quarantine it for 4-6 weeks.
