Hello Lexie, and welcome to BYC!

Glad you joined.
Not really.
You want to shoot for as close to 1sq ft of permanently open ventilation per bird in the coop with more than can be opened up during hot weather.
You also want 1 linear foot of unobstructed roost space and 4 sq ft of floor space per bird in the coop. You want to shoot for an additional 12-15 sq ft in the run especially if you plan to expand the flock.
If your DH is in construction, he should be able to run a circuit out to the coop. It is very convenient to have electricity in the coop so be able to work out there at night. Or to have a heated water source out in the run.
