My wife is addicted to chicks and did back-to-back hatches for over a year straight. Every three weeks, she'd put new chicks into the brooder, move the brooder chicks into tractor 1, move the tractor 1 chucks to tractor 2, move the tractor 2 chicks into the grow out pen, move the grow out pen youngsters into either the main flock enclosure or bachelor pen, then clean out the incubator and reload it with new eggs.
I'd process the cockerels and she'd cherry pick the chicks, keeping her "favorites" and selling the rest when they got to about 3 months old.
She recently took a 3 month break but started the process again a month ago. We have week old chicks in the brooder and another batch of eggs in the incubator. 3 turkey eggs and 12 chicken eggs.
