While I can imagine it's disheartening for the diversity enthusiasts like myself, it's probably worth it to strategically ward off the nasty poultry illnesses of other places. Read a discussion on the price to import a bird from a "dirty" country (us) to a "clean" country (Australia) and it was nearly 5X the cost of the reverse. I have no idea the cost from European countries, must be similarly expensive if marans/favs are that... Circular?... In their family trees
With the exception of some very hard working and heavily invested breeder's programs here a lot of our imported breeds aren't even resemblances of their namesakes. Many of our marans shouldn't even be called marans according to definition, our faverolles have only been salmon for a couple years! They were assorted colors when I fist came across them.. that's not a salmon faverolles, it's not salmon!
Our isbars and cream Legbar have loads of issues and are still super expensive. But I'll stop taking for granted that I can go get about any breed I want within a couple hundred miles.
Stop back in with pics of them if you pick up new birds, I love stories with conclusions!
