My girls came from the one u mentioned. I got my RSl at pol and they came from PA so I know they were. Only bred to lay more eggs. This makes me sad.
Now how can birds that have parents not be hatchery stock? Or does it take several generatins to breed that out? This is interesting to learn this.
I'm not sure what you mean-are you referring to what I said about Olivia? Her sire was a crossbred standard Cochin x Silkie and I have no idea if those two breeds in him were hatchery stock, but most likely were. Olivia's mother was either direct from McMurray or hatched from McMurray parentage (got the eggs she hatched out of from a friend who had hatchery Rocks and this elderly rooster whose origins weren't known).
Not sure how many generations you have to go out from the hatchery origins, or if there is any set "distance" that would make the bird much less susceptible to internal laying/egg peritonitis. I just know that hatchery stock is definitely not bred with longevity in mind--really, that wouldn't help their business anyway, to have hens live a long life, if you think about it. I just know my experience. I have breeder birds who are three years old and older who have never had one single issue with egg production. I do have two 4 yr old Brahmas, both from that hatchery, who haven't had issues, but then, Brahmas are not what most folks get who just want eggs every day so they may be in better overall genetic health than the common production Reds, Rocks, Orpingtons and Wyandottes.
