Weird Spots on Eggshell?

[ChickyCh00k]

Does anyone know what the deal is with these weird spots? They aren't soft, it's not blood, and they don't seem to all be from one chicken - different sizes/shades (but I get one that looks like this at least a couple times a week).

What do the insides of the shell at those spots look like?
Probably just a shelling glitch.

That's a great question! My husband is the cook in the house, so he does the cracking, but I'll make sure he uses one of those eggs and check it out when we have breakfast!
