I've gotten my chickens either as pullets or fertile eggs from local "breeders" - meaning either people who call themselves breeders but are pretty new at it, and some of their breeds were probably hatchery stock, or people who have a lot of chickens and sell fertile eggs. Out of my first 3, a wyandotte got EYP @ 2 years (guessing hatchery stock there); but the EE and BCM (breeds she cared about) are still healthy and laying strong at 5 years old. I started with pullets in order to avoid roosters. When I decided to get fertile eggs (my BCM is a broody and raised the chicks wonderfully), I went for an unusual breed, CLBs, in hopes it would be easier to find takers for the roos. Since the woman I got them from breeds for eggs, I don't expect they'll have great longevity - 1 of 4 CL girls, who was ridiculously productive, just died of ovarian cancer. The other 3 are 3 years old and laying well.
I will go to local folks in the future, though I will try to hunt down high-quality breeders, as my top priority is healthy, long-lived heritage breeds, vs. high egg production in a flock cycled over every 2-3 years.
Based on my very limited experience, I'd heartily recommend EEs - they may have hybrid vigor - and BCMs. Auto-sexing varieties like CLBs allow you to get a day-old chick that is assuredly female.
