This looks odd?

So we're on day 16 for the d'Uccles & Serama, and I decided to candle today since Friday is lockdown.
I have an egg where the development looks off to me, but I havent been hatching for long, so I was hoping for some expert eyes.

With the rest of the eggs, the chicks are pretty much filled out in there, you can see movement and such, and look to be about what you'd expect for this point. This specific egg, the chick is much smaller and there's still tons of room inside the egg - i can see breathing and movement. Off to one side there is a darker spot? Not sure what it is, but I've not seen that before either.

1st picture is the chick, second is the dark spot (id like to add in that the dark spot is not attached to the chick, it's floating separately) and 3rd is again the chick.
I have a short video where I'm turning the egg, which makes it easier to see what I'm talking about, but i don't know how to post it.

Not sure if I should just remove this one from the incubator or keep it in there. Again, everyone else is right on schedule, size wise. Incubator is at 99f, humidity at 45%.

I apologize if I sound ridiculous, this is only the 4th time I've hatched eggs.

I'd leave it. It has veins still, so its not completely dead. I think you're just seeing two ends of the chick

Ok, ill keep it in there. I took a few more pictures - it looks like it's not attached in any way...but I mean it could be?
There's a lot of room in there still

Edited to add in that I added labels on the pictures this time

Yes I would leave it there. Mine all looked similair like that and I had a 60% hatch rate

Ok! I'll leave it in there and see what happens I've never had one look like this before - so ill see what happens and update after hatch day

Looks like it's smaller than it should be. But yeah, leave it, and see what happens.

Keep us updated

Good luck

Thank you ❤ I will! Theyre due to hatch Monday, so fingers crossed

Following! I'm a week away from my first hatch & very interested to see how this one turns out. My very inexperienced guess is that the spot could be a ruptured vessel, which may or may not be inconsequential. Keep us posted, & Good luck!!

That is an excellent guess! I certainly will - I've never seen a chick develop like this. Good luck on your first hatch! & ill post next Monday/Tuesday when everyone starts pipping
