How far along are my eggs?

I found my Cayuga duck hen sitting on a nest and discovered multiple eggs were fertilized. She was not in a safe place to nest so I decided to take the eggs inside to incubate them. I have 6 chicken eggs and 2 duck eggs. I’m not sure how far along they are. I found them on December 11th and here is the development today. I need to know what day I’m on so I can prepare for lock down. The chicken eggs all seem to be around the same as far as development so I assume they were laid close together. The duck eggs also look about the same.

There looks to be a blood ring.

I dont know ducks, but I would think the chicken egg is around day 10, more or less. I think avg. Incubation time is 28 days for ducks? So I would assume right around the same age, since the embryo looks smaller, but it does take longer to develop.

I thought that too when I first candled. It has delveloped a lot and is moving around in the egg. I believe it is just a big vein

5/6 hatched on the 29th and 30th. Unfortunately #6 died before it made it out of the shell The ducks are due in around 5 days and they are still doing good!
