Who laid this egg? A Dominique? A Buff Orpington? A Rhode Island Red?

Thanks for the info! Hopefully they'll all be laying soon so I can compare the three eggs side by side. Sounds like it could be any of the three...

I know the BO eggs are supposed to be more or less cream-colored with a pinkish tint.
The RIR eggs are supposed to be light brown.
Where should the Dominique eggs be in this range? In between?

THANKS!
