It's a breed, just a new, unrecognized breed developed by Hoover's that probably will never catch on. Every backyard breed, whether it be Australorp or Rhode Island Red, was once just as new as an Asia Black or Asia BlluE. I ended up with 16 Asia Blues by mistake when I ordered Australops from Hover and they packed the wrong breed in the box. They're calm and pretty descent layers. Very hardy, as I haven't had any losses after eleven months. Hardiness and multipurpose is what they were breeding for from what I've gathered.
Can you please post a few pictures of your 11 month old chickens.
There are other people here with new Asian chicks purchased from TSC recently and are wondering what the will look like as an "adult"
