Weird. I'll have to take pictures of my eggs tomorrow. I have 3 full grown Ameraucanas (aside from the new ones). One lays green, one lays blue, and one lays pink. The blue layer is bigger, but brown/golden speckled and the green is skinny and skittish and brown/gold speckled. The pink egg layer is white. I know that their feathers don't equate egg color, it's just how I know who lays what. Unfortunately, the blue egg layer also has some bumps on her eggs so it's not a completely smooth perfect shell.
...I bet it's considered a greenish blue...
Beckah, they sound like Easter Eggers. They are mixes of different breeds, without a breed standard. Ameraucana, and Araucana have a breed standard, its made by the American Poultry Association. Its called the standard of perfection. The colors you are describing sound like Easter Eggers. They are great layers, and are very hardy and healthy from hybrid vigor.
