Efowl, Hoover's Hatchery, and Purely Poultry are selling what they say is a newly developed dual purpose bird called the Asia Black Chicken. It has primarily black feathering that features green iridescence. It also shows a varying degree of red/gold on the neck, breast, and body much like the Black Sex Link female. Purely Poutry says the Asia Black harkens back to the Langshan, but at around 5 pounds and 4 pounds respectively for a rooster and hen, the Asia Black is about half the size of a Langshan. I've tried researching the Asia Black. But the problem is that search engines produce results about the Silkie and Ayam Cemani due to the common and vague nature of the Asia Black name. And there really doesn't seem to be much information on the breed out there. I have noticed that eFowl and Hoovers also sell a newly developed Asia Blue Chicken that seems to be about the same thing as the Asia Black Chicken. I'd appreciate anyone's experience or knowledge on the Asia Black as I believe a have a batch by default. I recently ordered Black Australorps from eFowl, but what was sent from Hoovers has turned out to look like Black Sex Link pullets. However, there is a cockerel or two in the group also bearing the markings similar to those of female Black Sex Links, so what I have is not Black Sex Link. ( The cockerels in my group appear to differ from the females only by maybe having a red band on the upper wing.). eFowl has admitted the screw up and has given me a full refund on my purchase. But they can't tell me what I've received by mistake. From what Hoovers was hatching at the time I got mine, Asia Black seems to be the only possibility. Again, I'd appreciate information from anyone familiar with the breed.
