Black Spot in Duck Egg

[Keeley]

So I've got a new batch of eggs, started with 10 but it's been a week so I've removed the infertile eggs (3) so now I have 7 eggs left. 2 of them appear to have small black dots where the heart should be. People have told me that sometimes it's the eye but I'm not sure and would like to know for certain what the dots are.

I guess no one knows. Could be the heart or even an eye either way looks like it's developing well.

1st looks like an eye
2nd looks like a meat-spot

But both look great!!!

Good luck!!!!
