Is this fertile or infertile

I don't get it, I do not have any roosters and I still get once in a while a blood spot or a white spot in the egg.

I think the blood spot is when the egg is developing the hen has a small bleed, and that blood is trapped in the egg. You don't need a rooster for that. Is the white thing you're seeing on the yolk?

My wife has done extensive research on why some chicken eggs are infertile and did a blog post on her findings.

yes it is

I am so glad this information was posted. I had read previously that the blood spot did not mean it was a fertile or diseased egg, but I have had a hard time convincing some of my friends. I have saved your information to share with them. Thanks.

So what do you think about the egg on the right??

Am I correct in believing that the egg on the right looks to have been sat on for a day or two, and this is the developing embryo?

By the way speaking of bacteria.... Can the new product Vetericin be used by poultry? I figure it can be used on equipment as a disinfecting spray. It says nothing on the label one way or the other about using it directly on the birds. If you are unfamiliar with it it is a clear spray that can be used on wounds, burns, hotspots, sterilizing equipment, sterilizing udders and be used on horses, cows, sheep, goats, pigs, dogs and I think even cats. I have used it on myself when cutting myself working with the animals and it works amazingly. You heal twice as fast. Only using Neosporin and Triple-antibiotic ointments come close to comparing. It is expensive but worth every penny.

My thought was that it would be good to sterilize incubators and maybe spray on the eggs just before they go into the incubator. Unlike bleach it does not have a corrosive factor (it is used in wounds after all). You wouldn't wipe the egg just spray it and put it in.

From my understanding, vetericyn is a weak bleach solution.
