Hello! Not sure which one of my gals left us this egg??? We have an older Easter Egger who lays every now & then. An old Americauma Cross who stopped laying a while ago, and 2 younger Americauna gals who may be just starting to lay now. Those would be the only 4 of the 16 hens we have that lay that color egg. My question is..... why is it so big? Next to it is an egg from my Barred Rock (Barbie) and a lemon. Dang thing is super heavy too. Is this normal?
