I might go ahead and check into it and help out with a little preservation later on, but I still feel that any chicken is valueable, if well kept and healthy. They all can take care of our families if we take care of them, so I can't fault anyone for getting their chickens by way of the hatcheries, nor can I even conceive of putting a cheap price tag on my current stock....although not for sale.
If and when I do it, it will be something I might not even be able to explain, but my reasons would be closely related to everyone's on this thread. I can understand your motives and I completely understand having certain attractions to particular breeds. I might even be able to lay claim to having a heritage breed right now........I mean you can't find araucanas at the hatcheries.....none that I am aware of.
