We've been getting some ginormous eggs lately, I think from our largest hen "Big Red".
Egg collect a few days ago
This one was so big, it looks she had to do some extra pushing to get it out. (notice the middle is smaller in circumference than the parts surrounding it.) The egg on the left is one of our normal size eggs, which is a "large" egg, according to the size of eggs you buy at the store. The one on the right is so large, I thought it might have 3 yolks so we decided to video as I cracked it open to see what indeed was inside.
The 2 yolks on right side of the pan came from the enormous egg. You can see they are larger than some of the "regular" eggs.
