Right now I have 1 adult bantam EE currently sitting on eggs, 1 1 year old Ameraucauna hen who I believe has always laid green eggs, 3 Black Australorp and 3 Ameraucauna pullets, all born approx. 5/5/08 so not quite 3 months old. My question is where did the egg below come from? The pullets should all be too young to lay, right? But this is not only the wrong color but also very small (slightly larger than a 9volt battery) to be the Ameraucauna's egg. What do you think, is this from one of my BA pullets?
