I'm heading in the same direction you are, warmfuzzies, although for possibly different reasons. The goal (as in something to aspire to) of our little operation is self-sufficiency. That is less about rejecting outside influences or saving money as it is about lessening our carbon footprint on the planet. Sustainability (environmental and otherwise) is our long term goal. The less we import into our micro-system (this includes birds and feed), the more self-sufficient and self-sustaining our project will be.
Example:
We use Jon Jeavons' biointensive approach to gardening. In this system, it is considered a negative to import even seeds or compost, as those items would require outside influences in order to maintain them. Plus, if we import topsoil or compost from somewhere else, that is stealing resources from the land or area where that is found or developed, not to mention the fuel or packaging to get it here. You instead save your own seeds and raise your own compost crops and build your own compost.
So, we will be finding a good meat bird, to be kept as a separate flock from our table egg hens, just for the purpose of producing our meat birds. Our goal is also to feed them only feeds we can grow on our little place, at least what feed they need aside from free ranging.
This may not be attainable, but it is the goal. Short of that, we will get our birds and feed and compost and what have you as locally as possible, supporting our local economy (and fellow BYCers) which still lessens our environmental impact.
