Healthy development? Incubating eggs growth day 7

[gibsosyd]

Hi everyone! So I started 3 eggs 7 days ago in my mini chickbator incubator and I'm wondering if the growth of this chick looks healthy during candling. There aren't pronounced veins like day 4... Does it look okay? Thank you so much in advance!

Day 4

Day 5

Day 6

Now my day 7 pic I just took-

Do you see any movement? Usually at this stage embryos are pretty active. I usually see more blood vessels at this stage, but it does look like the embryo grew somewhat since days 5 and 6 so it may be alive.

I don't really see much movement. It looks like the embryo is forming into the c-shape which is a good thing?? But it seems to be a darker pigment red than yesterday. This is my only Svart Hona egg I have so I'm really praying it survives!

Here is it today at day 8 :/ any input will help!
