HP spalding eggs will be as hard to find as pure greens to be honest. Just some advice when it comes to greens and spaldings, there are many breeders (I will not call them out by name here as that is not fair and not what this section is about) that will sell spalding eggs and call them HP or emerald's (by the way the emerald name is way overused for lesser % birds now) and after you hatch them, you really won't know how high the % really is until months/years before you can really tell when they are colored up. Spaldings are great peas and some can fool the experts, I would advise you to buy chicks instead of eggs and from a reputable breeder that has fine Greens such as Rocking B-A-B Ranch I have some of their imported Muticus bloodline birds here and there is no comparison to Spaldings, as the breeder stock they have are fine birds and about 5 feet tall each. Contact Josh Nelson I am sure he can set you up and he ships, they do not sell hatching eggs though. I hope this helps.
Edit: PS: Consider your climate when it comes to pure or close to pure greens. They do not tolerate the cold and start losing toes in the really cold climates so you may have to accommodate with warm shelter and heated roosts or get lower % spaldings.
