Actually this isn't true, I grew up hearing it but recently read an article about it. So the real answer:
Blood Spots
Also called meat spots. Occasionally found on an egg yolk. Contrary to popular opinion, these tiny spots do not indicate a fertilized egg. Rather, they are caused by the rupture of a blood vessel on the yolk surface during formation of the egg or by a similar accident in the wall of the oviduct. Less than 1% of all eggs produced have blood spots.
Mass candling methods reveal most eggs with blood spots and those eggs are removed but, even with electronic spotters, it is impossible to catch all of them. As an egg ages, the yolk takes up water from the albumen to dilute the blood spot so, in actuality, a blood spot indicates that the egg is fresh. Both chemically and nutritionally, these eggs are fit to eat. The spot can be removed with the tip of a knife, if you wish.

RE:
if an egg yolk has a red dot does that mean it was fertilized and could have been hatched?

To a certain extent you can get some red dots in chicken eggs because they've been fertilised, but it's perfectly possible to get red dots and a little bit of blood if they're not fertilised. That's because the egg gets made in the chicken's oviduct. It descends the oviduct and has the shell made around the outside. Sometimes as it's going down the oviduct, a blood vessel in the wall of that oviduct in the mother chicken can burst and spill out and get into the material that's being laid down in the egg. This means that you have a little blood spot in the egg that then gets wrapped up in the shell. Most egg producers shine lights through the eggs in order to see if that's happened and weed them out. Pale eggs are easier to weed out than the brown ones, which is why you tend to see it more often in brown eggs. It's not in any way pathological having the spot in them and you can eat those. They're harmless.

Sometimes that is what it means. That the egg was fertilized. Sometimes a little blood passes from the hen to the egg, that natural. If you are buying eggs from a supermarket chain, there never would be any fertilized eggs. If you get your eggs from a country store or from a local farmer then you might get fertilized eggs.
It's no big deal, anyway. Many millions of people eat fertilized eggs.

No it doesn't. A chicken egg...bluntly...is the same thing as when a human ovulates. Within the egg itself, there are the means by which to produce blood vessels. Eggs from a chicken farm are not fertile because there are no males around to do that. The females ovulate like any other egg bearing animal, and that's what you get in your grocery store. They don't need a male around to ovulate, therefore egg farmers don't keep roosters anywhere near the hens they use for commercial egg production. The eggs you get are not fertile.

NO! You have to have a rooster to make the egg fertile.

Its just a blood spot - and the egg won't do you any harm either.
