Well the only way to know for sure is to breed them. It could be something cool, or it could be just a bunch of normals. I agree they do look a little odd. If nothing else I'm sure a local pet shop would take the babies off your hands if they proved to be just normal but there is always that small chance that you have a new morph hiding inside them. Either way you wouldn't have to wonder anymore, I say breed them and find out.
