Commercial egg-laying hens aren’t going to be let anywhere near a rooster, so you’re not going to get fertilised eggs from the store.

But… unless they’ve been incubated, the only difference is a white spot in the yolk.

If you get eggs from a recreational / family farm, you may well get a bunch of fertilised eggs — you wouldn’t notice unless you knew what to look for.

That's why it's rather obvious when they are fertilised. Because you actually will often have to consciously go out of your way to ask for fertilised eggs, usually specifically for chicken breeding purposes.

Sorry for that I could have made it more obvious. Haha.
