Yes, budgies are highly flock oriented and they love living together. You only have a problem if you have three or five of them because even when it's an odd number, if you have, say, seven of them, they get along.
Great, I'll keep this all in mind if I decide to. I adore watching them...especially when they fly around here...and over Pod's head, at which point he will whyne a little. Adding humor to my day.
