Yeah, with 10 budgies I can't say my self control is awesome.
It's about knowing what is best for your flock. When my new birds are introduced, dynamics will change within the flock but I mostly don't let the whole flock out together only rarely. That was with 8. So with 10 I likely will resist doing all of them often.
I think it's great you resisted. There's always plenty of time.
