The shell seemed to be normal thickenss but, when I cracked it it wouldn't crack cleanly. As for the yolk......
None=no yolk at all, only white. So the "pootie" egg would have not hatched at all. It was the size of a quail egg. All of our EE's are standard size and at least 2 years old as as old as 6 years. I really would love to have lots of normal sized eggs-not into white-only omellettes.
