Yeah, wrong forum, but I'll help ya out anyway.
1. Coco-fiber stains eggs, but to my knowledge shouldn't harm it otherwise
2. the eggs look undercalcified. Are you sure they're even fertile? If the ones by the penny are older, they look like they're more likely fertile, but the bottom ones look too odd.
3. You might be keeping the incubating substrate far too wet. The eggs shouldn't look wet 24/7. Too much moisture can drown the embryo. You might want to try something like hatch-rite or superhatch. It's a bit easier to control, especially if you are new at this.

Here's a batch of eggs on hatchrite. All of them hatched out, the one on the bottom left had been left in the lay box too long and was under-calcified, so it was easily dyed. The one on the top right had a slight under-calcified spot, which kind of looks like an odd webbed crack in the egg. It hatched out just fine though. I had gotten one batch of eggs that look like the bottom ones in your picture, and none of them made it. They were too under-calcified.
