So, what makes a flock of poultry sustainable? What is standard-bred poultry? If you purchase chicks from a hatchery, are they true to the breed? Why does every hatchery sell Rhode Island Reds and they all look different? Why do the Cornish Cross meat chickens have so many problems? Raising standard poultry is the only true way to improve the sustainability of quality local food while preserving the strength of Heritage poultry.
