To OP: Welcome to BYC.
Have you checked your state's thread? Many folks have POL pullets or are thinning their flocks of hens to get ready for winter. If you go that route, be sure to get all of your birds from the same source at the same time.
If local feed store is getting any more chicks in, that would be a viable option. If you go that route, have your coop set up and ready to go, with electricity. You can then brood your chicks in the coop. Much safer for you and less traumatic for them. I recommend a heating pad brooder: more natural, safer, and will work in all outdoor temps.
I would not order chicks in from any hatchery => feed store. (that you would then pick up at a feed store) My experience with this option has been dismal. I arrived at feed store to pick up my special order chicks (which were part of a larger shipment) to find that the chicks were in a total panic b/c the employees had no idea how to meet their heat needs. One of my chicks was comatose b/c it did not have enough heat. And I was told that there was absolutely no guarantee. If a chick died in the parking lot, there was no replacement or money back offered. If you order from a hatchery, eliminate the feed store middle man. Hatcheries offer 48 hour live guarantee, as well as limited gender guarantee.
Or you can do as Arknaf2 suggests: build a bator, and hatch local eggs. You can build a bator for around $20. Just be sure you have an exit plan for all of your cockerels.
No matter what you do, have your coop ready first. Recommended space for back yard flock is 4 s.f. in coop, 10 s.f. in run per bird.
