Is this egg bad?

[Hannahdoesntexist]

Both guesses about the two were correct. First one was dead and second was yolk but had blood vessels so maybe a day or so of developing

The two last photos?

Is there any farms close enough to drive over and buy some eggs?
Any neighbors that have chickens?
If you aren't worried about the breed maybe that's the way to go.

The top photo and last one. Second photo I am giving another day since I saw some decent veining and possible growth. It’s a pretty dark egg so it’s hard to see it clearly. I’ll have a look in the morning

 

[The Happster]

Ok, great.
I'd keep it just in case.
I'd be expecting more life for day 8, but I wouldn't throw it yet. You might be surprised.
Hopefully you get a hatchling.

 

[Hannahdoesntexist]

I hope so. I'm looking into getting some day old chicks from a local farm at least just in case this one fails too

Have you checked the temp in your incubator with a calibrated thermometer? What kind of incubator? Something is wrong with your incubation method, if that many developed and died.
