VIDEO ^^

I have another Egg and its doing fine, this one is just a concern, i only see a faded dark spot as you can see in video and a few like marks, dont seem to be veins at all or a embryo.

Close up photo of marks:

hard to say ..if it looks clear compared to the others its prolly a dud, but i usually leave them in these days .. i'll put a small mark on questionable ones .. 9 out of 10 times theyre duds but theres always that surprise one .. if you notice it obviously seeping then get it out ..

So should i leave it to see if its still alive and changes? ive incubated for 10 days same as the other one and it doesnt seem to change much only got a darker spot and few marks thats about it, im sure some take longer to develope?

I recommend leaving it in until about day 12, if it doesn’t have any clear veins or movement by then I would take it out.
