Great thread. My Hubby and I often discuss this.
We have only 2 acres, with 4 goats (2 does in their backyard pen, 1 buck with a wether in their frontyard pen), and about 40 chickens. We make about $20-30 a week from egg sales that goes to pay for their feed. We have just this year planted lots of fruit bushes and trees. Was told we could use tree leaves (from like oak, maple, willow, etc) for the goat feed... wonder why we never considered that?
Also, we're sprinkling alfalfa seed on our back acre so that when we "lawn-mow", we'll have alfalfa in the mix. Will press as much as we can into blocks for the goats to feed on during the winter. Plus we grow sunflowers, corn, soybeans for us and the critters.
remember that we don't HAVE to get our protein from animals. My son loves sunflower seeds, green beans and eggs, as well as my homemade pork-n-beans. Oh, and our goat milk.
I do need to get metal trash cans to store things because we have a horrible mouse problem, but those suckers are expensive!!
Anyway, my 2 cents. Great topics. Keep 'em coming.
