Bird egg identification

[LittleBigBantam]

So 3 weeks or so ago I found a double yolk egg and thought it was a bird egg :/
...... but this time it's different!! I was walking around when I found a random bird egg. Its smaller than all my eggs, and none of me hens even lay that color. It also was laid overnight or really early in the morning, because it was not there yesterday. I saw it around 9 am, and I just let the chickens out not even an hour before that. I live in upper michigan and its breeding season atm here. I'll post pictures

One of your chickens could have layed a smaller egg that day, but I do not know what species of bird could have layed that egg.

Velociraptor.

Hmmm. How would I hatch that

Eat it.
