Blood Ring vs Blood Island?*Pics Added*

[GabCar]

Morning friends! I am on Day 8 of my first attempt at hatching. I am hatching green eggs (Welsummer X Cream Legbar) and they are very hard to see anything through. Can someone please give me a way to identify a blood ring vs. a blood island? I thought one was a blood island and then spotted very clear movement. Can anyone give me some schooling based on their experience?

That egg looks okay to me. With blood rings, it's like a solid dark line in the egg. It doesn't always go the whole way around but it is there. I'm not sure what a blood island is?
As long as you see veining and occasionally movement, the egg is on track.

Hard to tell by the pictures. I would try candling again in a few days.
