I've got buff Rocks on order, so I've been reading everything I can find on the breed. That's how I discovered there are also Columbian PRs and Silver-Penciled PRs, neither of which I have ever seen. Is anyone breeding them who could tell me a bit about them? I'd love to see some pixs and hear about how well they lay or any other information. Does anyone know of a source for either color? I had been planning to order some Partridge PRs, but I am fascinated by the idea of these 2 colors. Thanks!
