Actually Malay were used in the making the Cornish Game Chicken, in which where used to make the Cornish X. A specific Dwarf gene came from the Malay. This one is different since it has created an infertile Dwarf that don't produce eggs.I dont think that would work anyway. If she is for sure pure maylay then she would carry no dwarf genes. I would guess she most likely is small due to a mutation.
Her full blooded brother is a Giant.
