No choice of breed and these are all males of Heavy Breed Chicks (Heritage male poultry.) Photos in the gallery are some of the birds you may receive. Generally these old time heritage breed male roosters take 4-5 months to reach 5-6 pounds of live weight. They do not have the growth rate of modern day broilers and take a longer time to harvest weight. They will have a lean meat and not the legs and/or heart issues that some of the modern day broilers have.
