Maybe? Maybe they don’t have enough pigment.
That would be interesting.
but females seems to be tricky to identify as good vs bad
Is there any reason for that? I know poor-quality Lavender Orpington males make my skin positively crawl. Usually with females I notice it in the tail pretty easily. I've also noticed the birds bred to an English-type don't seem as prone to exhibit the fraying. I wonder if that's because English breeders take the time to cross in Black Orpingtons, while most people breeding American-type Lavenders are just churning out as many horrible quality birds that have the right color so they can sell them for a quick buck.
