Welcome to BYC! Where are you keeping that may 6 week olds, without overcrowding, if your coop isn't ready for them? Your going to need at least a 80 sq foot coop with no less that 20 sq foot of ventilation. (That doesn't include nest boxes.) At least one side screened, with 19 GA 1/2" hardware cloth, would be best for your climate.
You're also going to need a covered area for the feeders and waterers.
