my duck has lay two soft shell eggs after a hard one

[TaylerRae]

hi there,
my duck Mango has laid a perfectly fine hard egg this morning.
however this afternoon she’s laid a soft shell egg followed by another one less than an hour later.
she’s 2 years this november so it’s not her first lay. she has also got a good diet, layer feed eggshells and mealworms and we’ve never really had this issue with her before.

the pic attached are the soft eggs in question if that helps at all. thanks!

Welcome to BYC.
Occasionally a duck may lay a soft-shelled egg due to other reasons not associated with calcium intake. More likely there was a small glitch in her reproductive system that disrupted the egg formation process.
Unless this continues to occur regularly I would leave her be. If it does, please post back.
