Not arguing, but banties lay banty-sized eggs, about 1/2 to 1/3 the size of a regular hen egg. As far as I know (could be wrong) the silkie is a true banty - never heard of a standard size version. Full size green eggs are usually attributed to "Easter Eggers." There is an Aerocana, and a variety McMurry hatchery sells as an Ameroaucana (spell?). It is not really a breed, and memory fails me, but I tried to straighten out this conflicting information a few years ago - there is a lot of confusion. I used to have a blue egg layer (lovely powder blue), and an olive green egg layer a few years ago. As far as I could tell from the research, both were "mutts." The hatcheries have been mixing the original aurocana breed (spell?) to get brighter hues in the eggs.
