Now I need to find some examples of what color leakage looks likeThe easiest way is to know the parents. Usually dominant whites now will only result from birds who came from a Paint x Paint crossing, and even then it's only a 25% chance of this.
But yes, if you don't know the parents the only sure way to know is based on what color chicks you hatch out like @LynnaePB said above.
My bet is that you will hatch out mostly black chicks with some leakage, and a couple partridge. All chicks will carry a recessive white gene but that won't effect anything on the chicks color.
I hatched an accidental black x recessive white pairing. The boys were black with gold or silver leakage and the girls were solid black.

Thanks!
