Unusual veining - or not?

[Hestia]

I am incubating a batch of eggs in my Brinsea eco, which requires hand turning them.
On day 2 I unexpectedly had to go away for a couple of days. This meant the eggs weren't turned for nearly 30 hours. When I got back I started turning regularly again.
Yesterday was day 7 so I candled. I had 6 unfertilized, one developed but with a blood ring and the rest developing.

However, in the developing one's, all the veins were on one side of the egg.
I've only incubated a couple of times and the last time was months ago, so I can't remember if this is normal or not.
Are the embryos stuck to one side of the egg from that day and half of not turning? What are their chances of making it to hatch?

Sometimes Early stages the veins appear to be on one side. I think your eggs should be fine.

Normal

No, not that quickly. There are benefits to turning them so I don't recommend not turning them without a reason, but the yolk or embryo will not settle that fast. Just turn them as normal.

What are their chances of making it to hatch?

As good as they ever were. No harm done.

My quail eggs get sort of “sludgy” on days 6-8 or so, the contents move but slowly, say thirty seconds to sludge into the lower half of the egg, after a dozen hatches with 90% hatch rates it just seems to be normal development but it totally freaked me out with my first hatch! What is bad is “sloshy” eggs where the clumpy stuff swirls around easily, often a mid to late quitter.

Thank you for your replies - I feel reassured now and we'll see how the incubation progresses.
