I'm not sure about the egg men being seperate entities...but I think you're actually right about the Gaster Shard thing. Remember the "I'm holding a piece of him right here" Goner from Undertale? He's holding an egg. I think the Egg Man Gaster is handing out pieces of himself.

Gaster can be both of these

Eggman is a part of Gaster
This NPC is missing their hand, I've never noticed that until now. Interesting.
