I would like to get a heritage breed. One I was interested in is the Cayuga duck. I see them different large hatcheries, but they are on the threatened list on the American Livestock Breeds Conservancy page. There are chickens that are listed as threated too that I see in the hatchery catalogs, like the Lakenvelder. I am just wondering how a breed of chicken can be rare or endangered when I can find it at many of the big hatcheries. And if I buy those birds from the big hatcheries am I really helping to save the breed?
