Help on day 19

[jess9512]

I need some opinions I took these pictures today on day 19 of duck eggs . I'm a first timer so what I think jm seeing may not be what I'm seeing ... I probably candle to much but I'm excited and have an excited 4 year old. On the morning of day 18 all 7 looked veiny and healthy and moving. On the night of day 18 I believe I have a blood ring.
And on the other egg it's saddled I think is what it's called. But I think it's to late to do anything
