chicken or duck egg?

[Ardizzone7]

This week I have found 2 eggs under the coop. I have chickens and ducks that are just old enough to lay. The eggs are a creamy white with very smooth shells. Are they chicken or duck eggs? They are the size of a medium egg you get at the grocery. The chickens I have should lay brown eggs. Are these duck eggs?

If the chickens are supposed to lay brown, I'd say they're duck eggs. The first few months, most ducks will lay a smallish egg about the size of a chicken egg. It will get gradually larger as they mature. You may also find weird ones occasionally early on--eggs without shells, teeny tiny round ones, ginormous ones, funky textured ones, and so on. Their systems are still figuring things out.

Of course, if you post pics we can be more sure, but those definitely sound about like early duck eggs. Congrats!!
