Spot the Large Egg

Any ideas?
These appeared in the coop today.
Who guessed the one on the right?
Wrong.
The one on the left is a “large” egg (based on normal egg size rules).
The one on the right was also produced by one of our girls.
I think it came from the one with crossed eyes and the awkward walk…….
Will it be a double-yolker?  Update tomorrow when we crack the case….
