Small duck eggs

[Vanillaandbean]

Hello everyone so I have three females that are at the age of laying and they are khaki, jumbo Pekin, Rouen well one of these ladies are laying and I’m not sure who but the eggs were big but now they seem to be getting smaller if anyone knows why please tell me.

Were the large eggs double yolkers? Young ducks often lay them early on and then settle in to laying regular eggs. When they get older the eggs will get bigger but not as big a one with two yolks.
If the big eggs only have one yolk, the other eggs may be a different duck?!

The large ones were only one yolk but I’m only getting one egg a day so I’m not sure it’s from another female pretty confusing
