I just ordered pearl white leghorns from Murray McMurray hatchery and while talking with their customer service they mentioned that they don't recommend them for breeding. Are they hybrids or why wouldn't you breed pearl white leghorns? I have 4 of them already in my current flock and I hadn't expected to like them because they seemed "boring", but they ended up being my favorite chickens. They have a fun temperment and are easily my best layers. I have 4 of them and get 4 giant white eggs every day. So what kind of offspring would I expect from breeding a male PWLH to a female PWLH? Would they not lay as well as their parents? I'm primarily wanting to breed for egg laying ability. Thank you!
