I talked to someone once who said they got some eggs from Banko. He was telling them that he had had them since the beginning, before the ban, and had bred them himself until they were as good as they are. The person I talked to said though that they "were sworn to secrecy" which seems odd to do if he had the birds legally, and that he was describing them as having very different plumage than the other lines in the country, almost like hair over the bird's neck and shoulders. This person had been sent 3 eggs by him. And he told this person that the original birds "weren't even supposed to be in the USA" which does not sound very legal to me. It was also said by this person that the reason he doesn't sell them is because they are his chickens and he "doesn't want them to get out". So that's all I know about it.
Yup, there's that, too. Like I said, it just raises more questions. It just doesn't add up. And they are getting out there because he is making a mint off them and he is putting them out there. From what I've seen, they are good looking birds, but they still have the same issues and flaws as everyone else's AC.
This line is one reason people are now claiming that GFF AC are mixed, and that only "real" AC are hard feathered with dull sheen. No greens or blues or purples allowed.
