Duck Egg Striations

[Natdallard]

Hello, my ducks are one year old and laying eggs daily. I just recently noticed one of the ducks lays eggs with very visible striations going all around the egg. Is this normal, or should I be concerned about certain nutrients? The other duck's eggs do not have the striations visible so I am just wondering. Thanks!

Welcome to BYC!

I've seen those and I have no idea what causes them.

Romy lays those, and she seems otherwise fine. Hazel's eggs have small ends that are just a little off center. Sieben's eggs used to be nearly as round as a baseball...
