Hi there, Sassy13!
Once the Covid stuff recedes a bit, the poultry swaps will resume (although I think the one out in Edgewood does pop-ups). There are two that I know of: Edgewood and Belen, and then the occasional one at Millers Feed. If you're on FB, there's a New Mexico Poultry Swap page that lists all the birds, goats, pigs, etc., that folks have for sale.
I hatch out in Corrales. My Easter hatch sold out, but I have 28 eggs of Black Copper Marans and Olive Eggers scheduled for 5/24.
Hatchery birds are, well, hatchery birds. The gene pool there is pretty inbred, so a higher risk of deformities. I've heard both good and bad about Privett, who happens to supply most of the local feed stores with their chicks.
There's lots of good coop ideas (in fact, hundreds of examples) on one of the BYC pages that deals with coops. It's divided into Small, Medium and Large sizes...most all are homemade.
Welcome to the world of chicken raising! You'll learn about chicken TV and chicken math. BYC is full of enablers!
