Has Molly laid her first egg?

Have been away this weekend and returned to find 5 eggs in the nest boxes. Now, for the life of me, I can't remember whether I removed 1 or 2 eggs on Friday before leaving. This is important because if I removed 2, then the fifth egg could well be Molly's, however, if I only removed 1, then the fifth egg could be Kiev's from Friday. I thought that Molly's eggs would be white (because her ears are white...........there is logic in this, honestly!) but none of the five eggs are white, so maybe it wasn't Molly's after all.......
