Buy Rat Graves Leiper, These are from Rat Graves out of Oklahoma. We have had them for about 20 years. They are out of his double-right bloodline. I believe they are as good of a Leiper blood as what you can find. If I thought there were any better I would have them. Most will come green-legged, but I will occasionally get a blue leg. I prefer and try to encourage the darker red hackles on our Leipers.
