I believe it's 1/4 chances that you will get a Peach. But that's theory based not reality.If you just want to play around you can breed the Purple to Cameo to make splits that you can raise to later to breed back to the mother hen and if you get lucky you might eventually get a Peach in a few years. It isn't like mixing paint, the stars have to be in alignment like the alleles on the chromosomes have to line up just right to get certain traits.
