Does this look normal?

I honestly don’t know if I’m being paranoid. My 4 month old duck, Clover, has developed a saggy underside in the last few weeks. I’m really hoping it’s not waterbelly. I do have a duck with water belly and that duck doesn’t look like Clover. I also have seen Clover eating oyster shell out of their separate oyster shell dish, and I assume she is too young to lay so now I’m worried she could have organ damage from too much calcium.
I’ll try to get better pictures but she is shy.
Thanks!

It looks normal to me, some of mine will get that. They will get that sagging if they're laying or close to it. I would guess she's just getting closer to laying and that's causing the sag. I wouldn't worry about it but just monitor her closely.
She is definitely getting close to laying age! Mine started roughly at 5 months old.

Thank you! This is very reassuring. She’s such a cute duck I would hate to lose her. Another sign she may be close to laying is she likes checking out the nests and chattering to herself while she’s in there. It’s very cute

I understand!
I'm sure she will be laying soon.

Thank you! I’m relieved that I am just being paranoid
