The source is the Facebook Ancona page. Me as well as several others post there often. The woman that runs the group is trying to get a group of people together to show this wonderful breed and get it recognized!
This past winter/spring a bunch of us were talking about the "standards" of the breed. Boondockers pitched in their thoughts, then talked about using magpies to breed back to anconas to better the breed, saying it was Dave holderreads idea. They posted a short audio script where Dave did talk about using certain anconas to breed to magpies, but it didn't say whether or not it was needed.
We asked boondockers said that they were going to separate some anconas and do this breeding. But when we asked them if they are going to sell these crosses as pure anconas, they failed to reply.
We brought it up and mentioned them SEVERAL times after and they STILL haven't answered us. And they've posted on the site a few times since so we know they are getting online but simply ingnoring our question.
So as an ancona breeder, again, NOT PROFESSIONAL. And I'll just say that any of us made the decision not to buy from them for that very reason. And there are now tons of Ancona breeders out there. I understand that all or most origianlly came from that flock when at holderreads, but you will likely be better off buying from a newer but more reputable breeder. That way you know exactly what lines they are and what they are "made up as"
