A breed of Ducken that looks like a chicken with the body of an egg. It is exclusive to Monster Rancher 3, but a similar monster, Piyoken (possibly the "hatched" version) exists in Monster Rancher Advance. It might be related to Chuparo.
So-named because it looks like a hard-boiled egg.

||"A rumor suggests there is a raw Eggukken and a boiled Eggukken, though it's probably just a bad joke by breeders who missed breakfast."
- To obtain an Eggukken in Monster Rancher 3, use the DVD Chicken Run (Special Edition).
