bragabit,
I think I'd wait at least a week and a half for your older 4. Then a week after that for the next 4. And then I'd wait at least 4 1/2 more weeks for your 4 babies...
Are you keeping all 3 ages in the same brooder?
We had to get a bigger box, than another bigger box, and then a 3rd. We just kept adding on, finding things to put over the top so they wouldn't fly out, and finally got them outside when it was time.
