For some reason quote doesn't work for me right now. Anyway, I only had a few take that long and they were late hatches without supplemental lighting over winter.
I think too many breeders have forgotten to focus on the production aspects of the bird and are under the false impression that overall size is linked to slow growth. If you're just raising for show it doesn't matter how slow it grows. While I do show my birds and indeed that's the main reason I have poultry, I believe if they don't perform as they should then they aren't good examples of the breed, it's lazy breeding.
Some of it is also likely due to the other two breeds in the class, the Brahma and Cochin being so slow developing, which is fine, those birds weren't meant to be dual purpose farm fowl, they were roasters, meat replacements for the turkey and are heavier birds than the Langshan.
I'm not saying they should be super quick to be fully mature, leave that to the hatchery mutts, but the pullets should be laying between 20-24 weeks, and the cockerels should be a decent meal around the 24 week mark. Langshans were a dual purpose farm fowl, think Rhode Island Red or Plymouth Rock, and should be similar (or superior) in growth and production.
I'll get off my soapbox, but really something I strongly believe, not just breeding birds to the Standard (because otherwise you just have mutts), but making them earn their keep.
