A friend of mine hatched three 'true' Americaunas...two lavender/blue, one black. Two lay beautiful true blue eggs. One of them lays an olive-colored egg, we think it's the black one. Fault? Throwback? Something jumped the fence? Who knows...but it happens.
I agree with Speckled Hen, I wouldn't include that hen in a breeding program. If she were mine, I'd probably call her an EE due to egg color.
If I were the OP, I'd be suspicious some other bird got in there, although from the picture, the hen looks true to sop - and quite pretty, I'd be happy to have her in my flock.
Coming from the dog world, I also think using the term 'pure-bred' for chicken breeds is somewhat confusing/misleading. SOP judging is all about appearance, not pedigree. Even Americaunas only need breed true 50+% of the time to be considered true. There's no stud book or closed gene pool in chickens.
