Who’s Egg is this?

[AnneLovesChickens]

We have several ladies at 5 months, both ducks and chickens. One Japanese bantam has begun to lay tiny cream colored eggs regularly in a nesting box. Today I found an egg on the middle of the floor in the coop, as if someone pooped it out while playing and continued on with their day. That or a duck found it somewhere and started playing with it. Either way, whoever laid it most likely laid it on the floor. Researching eggs has made it difficult to really understand each breeds colors and sizes and how they can vary even with the same bird. There are 3 possible culprits, which all are 5 months and include:
-buff orpington duck
-Brahma chicken
-ayam Cemani chicken
Anyone know? Picture below of the egg next to a tiny cream colored Japanese bantam egg:

looks like a duck egg to me., except for the size, but i would still go for duck egg.

She is a tiny duck. Here’s her playing around a couple weeks ago. She’s next to my female pekin of the same age, but I know pekin eggs and that is no pekin egg lol. It’s the size of a large egg at the grocery store.

It looks like a first duck egg to me too. They will get larger over time.

Is there any chance at all this could be an Ayam Cemani egg? Not that I doubt your expertise, because I surely don’t know, but the second one was found this morning in her favorite sleeping spot on the floor under the roosting stand. The ducks can get to this spot, so it’s still likely duck egg, but it’s weird isn’t it? The ducks also love the nesting boxes, so I always thought they’d lay in them for sure. That’s her spot and the egg yesterday was found about 6 inches from there. Ayam Cemani are medium sized birds, so idk if they can pop something out that size. Also, had to add more oyster shell around the coop, this egg is soft.

That reaaaally looks like a duck egg to me, cemani lay very light colored eggs. I would say that is also from the duck because of it's size. Congrats on the new layers!

thank you you're probably right. found it interesting that she laid it in a chicken spot rather than her favorite nesting box. then again, birds are weird lol. thank you again for your opinion!
