I think this is really strange. Is it?

I have 2 Khaki females and 2 Rouen females. Age unkown. I usually get 4 eggs/ day. Then I started getting 3 eggs/ day and 2 or 3 smaller ones every other day. Is this weird or just something that happens?

It could just be something normal. Once I got an egg that was only 15 grams! Alternatively, it could be a nutrient deficiency, so you may need to give the ducks some supplements.

Maybe they are old? Just a guess.

I opened them up. Odd.

Might be something in this info to help I know the tiny ones are called fairy eggs or fart eggs https://www.backyardchickens.com/articles/common-egg-quality-problems.65923/
