They all look similar- veins and movement - this one seemed a little more defined then the others but very close. There are two that seems darker inside egg. It seems like they are all close in development stage but a few look a little more ahead than the others if that makes sense.
We have Muscovy eggs in our incubator but are not sure of what day the eggs are on. We saved the eggs after their Mama was killed by an unknown predator. 😢 Any guesses on what day the eggs are on based on this video/pic?
