These are button quail eggs but one looks different, it looks like a coturnix quail egg or California quail eggs.
I recently bought these, does anyone know what kind of egg that is?
I am currently incubating them, so well see if it hatches.

Looks like a coturnix to me. I am not sure if buttonslay that color or not though.

Too bad it didn't make it, it died maybe one week of incubating. The others are suppose to hatch in a few days. Can't wait to see the baby chicks
