Can anyone tell me if this egg is fertile

Hi
I am wondering if my hen is laying fertile eggs and so cracked one that has been in the fridge for probably 3-4 days. She has the company of a young roo, so not sure if he's done his job or not. Can anyone tell from these photos? Thank you

Thank you. These were the best photos I could take. I think I might change the camera settings and see if I can get some better ones.
