I have a friend who raises Black Quechua/Olmec fowl and they do not have a laughing crow. Musical? maybe but all roosters have their own voices. I knew an old woman who raised Araucana's some 30+ years ago and she said some of hers had a laughing crow but at that time, breeders were only interested in the tufts and rumpless traits and the crow was lost. Indonesia is banned to import from by every other country that I'm aware of. Until they can get control of the disease in the birds there, no one will ever allow importation from them. Illegal importation might yield a few hatched chicks but they would likely not live long enough to crow or produce and could cause outbreaks here in the US, not to mention huge fines if you're caught.
Green Jungle Fowl are still very rare due to how fragile they are to raise. There are not many breeders and many are opposed to hybridisation because the pure numbers are so low. Even in Indonesia, the wild caught males used to make the Bekisars, often do not survive a full breeding season as they are so susceptible to common poultry diseases. Green JF also are not likely to breed willingly with domestic hens so artificial insemination is how most Bekisars are made. I have friends from Indonesia who breed them. The chicks are fairly hardy (Bekisars) and the cockerels have all sorts of interesting crows but the hens are generally infertile, none known to be fertile. Breeding a Bekisar male back to either a domestic hen or a pure Green JF hen can produce varying degrees of fertility in hens and full fertility in cockerels. I've been studying this for Years. I figure if there was a way to create a laughing crow line of birds here in the US, then those trying for the past 30 yrs would have gotten it done....maybe. Still, it hasn't stopped breeders from trying. I am no different. I bought my first Jungle Fowl this year. I'm hoping to do well producing pure JF (I have Murghi Murghi Reds, Greys, Sri Lanka and Greens) Task number one is to keep them alive through the winter here, where it can be bitterly cold (Yes, they have a building that I can heat) Next, to provide the right environment and change of diet to support breeding and fertile eggs. Then to successfully brood and raise the chicks. If I find I can raise plenty of these guys, I may give some cross breeding a try, with AI only, using a male I raise for this purpose so he can be handled and collected. The other thing about JF, the Greens that is, they are mature and productive at age "4".......so keeping them alive until fully mature can be an expensive challenge.
Then.....after all that, where does one go to build a laughing crow rooster???? It's all a crap shoot without a blueprint and I have asked many breeders of JF in Indonesia about the origins of the Laughing Crow and All I can get from them is that they are just like that, absolutely nothing as far as an idea about what breeds/species were used to make the first ones. And, they don't breed true....... And THIS is why there are no Laughing crow roosters anywhere else in the world but Indonesia, LOL Drives me nuts too.
