No choice of breed and these are all males of Heavy Breed Chicks (Heritage male poultry.) Photos below are some of the birds you may receive. We do not offer refunds or replacements on any of the free chicks or ducks sent with your order. 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.
