Marans laying weird colored egg

[aart]

So I think the marans who laid this egg has been laying a soft shell egg too. I’ve been finding broken eggs in the nest box but thought it was the brahmas, because the brahmas lay in a different area and I’ve been finding this egg where they lay. The shell has been soft and light colored. Again why I thought it was the Brahmas. But I have also been getting one egg that is a dark marans color. So one of my marans is still laying a dark egg. The other I think is laying this weird egg and a soft shelled egg.

I have been giving them yogurt and trying to boost their calcium. But since I didn’t know who was laying the soft egg I’ve been giving the yogurt to everyone. When I give the yogurt it helps for the next day. Then I find a soft shelled egg when I don’t give yogurt. Is she just not eating the oyster shells? Should I give all of them calcium citrate? I don’t want to start them on layer feed since they will be integrated into my flock next month and I’ll have to switch feed again then.

Are they not eating the Oyster Shell?
I'd try to get that particular bird to eat some,
give her a private breakfast with OS mixed into some feed like @rosemarythyme does.

I’m not sure what chicken it is. I just know it’s one of the marans. Since I’m getting two Brahma eggs a day and a dark colored marans egg every to every other day. But one of the marans is laying this light colored egg and a soft shell egg. She might not be eating the oyster shell.

Cage one of the Marans until she lays and you'll know 100% which bird is laying what.

For a private breakfast, 2-3x a week serve a small bowl (like 1 Tbsp is fine) of wet or fermented feed with oyster shell mixed in to the problem bird. If she does not like chunks of oyster shell, crush it up or use the powdery remnants from bottom of the bag. Should only take her minutes to eat and after that she's free to go.

Assuming her issue is simply insufficient calcium intake, you should see results in a week or two, and you can try reducing it to 1-2x a week and should hopefully continue getting good results.
