That's what I see thru many threads that a lot of people want. Since DP breeds have been neglected for meat and bred for egg laying enrichment. Even most heritage breeds have still generations to get back to what they once were. I remember my grandmother's RIR roo. He was a monster, but big baby. Swear he was 1/2 ostrich and 1/2 hippo. Wish I had his blood in my birds gene pool.
