Is this a chicken egg??

[5paceDandy]

So, I have both chickens and ducks and they are all allowed to free range the property. My chickens have been laying now for a couple months, while my ducks have not yet started (I don’t think they have at least). They each have their own, separate coops and pens, but because they free range there are a number of spots, both inside their coops and out in the yard that they have chosen to lay their eggs. Now, a couple weeks ago I found, what I thought at the time, was a duck egg(it was MUCH bigger than any eggs my chickens have laid), but it was in one of the outdoor spots my chickens had laid in and with a bunch of chicken eggs. I hadn’t seen any others like it since, until today. Today I found another big one, same size and color as the first big egg, but this time it was in the inside part of the chicken coop, again with a few regular chicken eggs. I have attached some pictures of the egg next to one of the larger eggs that we normally get and inside a regular egg carton, just to give context in terms of just how big it is. Is this a chicken egg? Or has one of my ducks started laying and doesn’t want anyone to know because she is self-conscious??

I'm guessing it's a double-yolk chicken egg, which are usually larger than the normal single-yolk eggs. But that would only be true if you have a chicken who can lay that color egg (it looks green to me), and if it does have two yolks when you crack it open.

Did you open the previous one? How many yolks did it have?

Do you normally get chicken eggs that color?

The color isn’t abnormal for my flock. I have something like, 10 or so different breeds in terms of my hens, though only 2 roosters, both the same breed. I didn’t open the first extra large egg, unfortunately (stupid, annoying situation, too long, but not interesting enough to type it all out), so I don’t know how many yolks it had, but I will make sure to pay attention when I open this one and will post an update!
