I got two dozen eggs for hatching from a guy off craigslist and day 6 none of them have developed. I cracked open one and this is what the yolk looks like. I have a loose understanding that there should be a bulls eye if it was fertilized but it's still not clear to me what I'm looking at. It looks like a white dot with a yellow hallo. That's not right... Right? Well I leave it to your expert opinions: fertile or infertile?
