introducing multiple males?

[Liquid]

I did it last year and only with Dominant and co-dominan gene males that way you don't end up with any hets.
Last year I had some young males that this was their first year breeding so I paired up a spider a pastel and a pinstripe withe a normal female and had 9 eggs.
Out of the 9 all hatched and I got a male Spider and a Female Pinstripe and the rest were just normals.
