How to tell if a duck egg is developing?

[theron]

I have 18 muscovy duck eggs in the incubator and i don't know how to tell if the ducklings are growing inside. They are on day 10, so if anyone has pictures i could compare my eggs to that would be great. thanks

I don't have pictures but you can google "candling eggs". It is the same for duck eggs as it is for chickens. You look for veining.

well we also have eleven chicken eggs in the incubator as well but since chicken eggs only take 21 days and muscovy eggs take 35 days to incubate i thought that the eggs would look different inside.
