Is my duck dead or alive? It has a black tail

[Chickyducks]

Hi.
A duck came to nest in our garden a while ago. She was very camouflaged and didnt know she was there for a long time. Sadly she abandoned the nest, we left the eggs outside for about 2 days hoping she'd return but didn't, so we've taken them in.
I've recently been incubating the eggs and there is no movement and they've failed the sink test, but I've been hoping there is still life.

3 of our eggs have died but this one has grown a wierd black tail-luke thing.

What is it and is my egg alive??

Thank for the help

The egg does not look viable to me.

The sink test does not work and is good at killing live eggs.
The eggs were dead before then though.

Ok, thank you but what is this black tail?

A blood vessel or decomposition

Looks like it quit developing...
The water test isn't reliable, though
And the goal isn't for them to sink, when they're developed like this, the goal is that they float a bit and its movement that you're looking for.
But this isn't accurate and can harm the egg
Instead, candling with light is much better.
