This is what I came to say. With other genes thrown into the mix, it's really hard to tell if you've got anything special going on or not. All three of my normals are pets, but depending on the female, I would use one of the males to prove out her genetics, or pick up another male that better fits her coloring and then just sell him after the season ends if she's proved out. They serve no other purpose genetically, unless you're looking to line-breed for a certain trait.
