How to check for fertile egg after some incubation

[Chickenfarmer101]

Hey ya’ll, I have two ducks that are mating and I’m incubating their eggs. Can someone either post a picture or tell me how to see if they are fertile and to check how many days after incubation. Everything online isn’t very good. Thank you so much!

I not sure when but I know you can candle eggs

I just watched this video today and I think it will help with your question. These are chicken eggs but they candle them at 4 & 7 days to check fertility. The video shows exactly what to look for.

If you post some candling pics on day 5-7 we can tell you! Usually by day 7 you can tell which ones are fertile.
You should see the embryo moving around and lots of veining should be visible.
