I think I see a bullseye, meaning it would be fertilized. Cold temperatures can render fertile eggs non-viable, so if it's still really cold where you're at, that's probably the problem. My first batch of eggs, I had a lot of eggs just never develop, due largely to the fact that the lows were well below 0 F at the time. By the time I could collect the eggs, they'd already been chilled.
Good luck!
