18angovem,Blue Creek Farm & Zazouse already explained it, but I wanted to add that when breeders are wanting a very high % spalding they take that 50% spalding and breed it to a pure green peafowl. Anyone interested in breeding their own high % spaldings must have green peafowl to do so.
As Zaz said somewhere down the line the 'mutt' genes will show up and there will be a very mad/confused buyer because they were sold pure greens and the birds looked pure but the offspring were obvious spaldings.This is what is also frustrating about Spalding breeding. You can have a nice 75% spalding like what Dany12 posted and an equally nice Spalding hen, but that doesn't mean the offspring will be as nice looking as the parents.
