This is actually pretty much the full version of my summary only I'm calling the imported birds EEs rather than Auracanas since they weren't what we currently know as Auracanas.
The issue I had with your post had to do with the current breeding program. The original imported birds didn't cease...
Sorry but that information is incorrect. Ameraucanas didn't exist as a breed until the 1970s. They were created by selectively breeding EEs to meet a standard rather than EEs being created by hybridization of Ameraucanas.
What a beauty! She's a hatchery type Easter Egger -- a descendant of the original landrace stock. And you're lucky to get one with such a bright blue shell, green is much more common.
