We're supposed to believe that they're this mindless horde that only cares about feeding, and yet they won't eat other zombies? I wouldn't expect them to be that picky, especially since a lot of zombies are just infected humans. Is there honor among zombies?

I don't watch or read zombie things, but I was always led to believe they... do... eat one-another, but they need healthy flesh to satiate their whatever.

depending on what you read, they will eat all living and dead things that aren't zombies
But they become infected as soon as they're bitten. They only refrain from eating other full zombies. And other zombies are the easiest targets. It would make more sense to me if like half the zombies were biting each other, but by sheer numbers some still happen to go after the living.
