ELI5: Can egg-laying animals (everything from insects to reptiles, etc.) have miscarriages? If so, what would that even mean, and how did we ever find out about it?

Yes. These are when the egg is fertilized but fails to hatch. You find out about it when you find an egg that has a partially developed embryo in it. That would have been something common when everyone raised chickens.
