Are all of these blood rings?

Hello! These all look like dying or dead embryos to me. I don’t see any movement ...they have to be at least 7-10 days. If anyone can give me some feedback before I toss that would be great! Thanks so much! On a lighter note. I took two new eggs from my Indian Runner and on day 2 in the incubator I can see signs of life! A tiny faint dot in the middle of the yoke sacs in both

Never having incubated duck eggs before I can't say for 100% But I'm sure that is a blood ring. Sorry.

Duds.

By 7 to 10 days there should be signs of veins and perhaps some movement. I don't think you've got a good batch there. Sorry.
