They just don't have the manpower to do what they're attempting to do with all the species/breeds/varieties as well as the corn, potatoes and other vegetables.
I'm only one person and it is a challenge to do justice to a single breed. You need a huge staff to properly maintain quality in virtually every breed of chicken, turkey, duck, goose, guinea and quail in the country.
It makes me wonder what their breeding pens look like. I can't imagine keeping hundreds of breeds separate with enough stock of each to maintain, let alone improve quality.
I was tempted to buy some Black Penedesencas from him but a couple friends got some and they were of poor quality and worse yet, some had 5 toes. I still can't imagine how that happened.
