Yeah, your thread title sure made me laugh too. Oh, shoot it's not that hard to figure out. LOL!
Ok, if you get a Partridge rooster . Of course with the partridge hen will produce all partridge babies , no brainer there. Blue hen will produce blue and black chicks that carry partridge.
If you get a Blue rooster, will get black/blue chicks from the partridge hen. Those will carry the partridge genes under the black/blue. And blue and black chicks from the blue hen.
If you get a Black rooster. Black babies with the partridge hen, but carry the partridge genes. Blue and black with the blue hen.
If you get a Splash rooster. Blue chicks with the partridge hen (again they carry the partridge genes). And blue and splash with the blue hen.
Anything bred together that is blue and carries the partridge genes. Then has a chance of producing a blue or splash partridge. This is how it usually works. Though some birds carry hidden recessives. That when paired one copy from each parent, can come up with oddities. Like recessive White. Or even Partridge which is also recessive.
Hey, whatever you decide. Have fun with it and good luck.
