When I zoom in on these photos it looks like photo two "might" have a blastoderm. There is a very faint ring. I don't see anything on photo one that looks like it's fertile, just a bare blastodisc. Can you hold some new eggs at counter temperature for a day or two before checking to see if...
This is just a thought, but should you be wrapping in plastic wrap? Is it possible that the fertilized zygote is suffocating? I don't think the eggs should be wrapped-- especially in something that blocks oxygen like plastic wrap.
