Permaculture is the way to go! Google it and start studying it. Great things to put in practice when it comes to avoiding the big expenses for animals - like feed! We range our chickens and feed them mainly compost from the kitchen scraps and dumpster dive hauls. They give us poop, make compost on their own, tons of eggs and meat. Electric net fencing running on solar is the ticket here. Same goes for our Berkshire hogs — free range them with rotational grazing in pasture and forests if you have it. I hate how the typical hog is raised in a tight pen — pigs need to root in the ground, it’s what they were made to do. Check out Geoff Lawton(permacultiure > http://geofflawton.com/) videos and Joel Salatin at Polyface Farms > http://www.polyfacefarms.com/speaking-protocol/joels-bio/ to get in the grove and make what your doing self-sustaining and profitable. And yes, it takes years and trail and error to figure things out for your particular resources and needs, but once you do, it’s like you were re-born. The cool thing is it can work on big and large scales. The self-satisfaction you obtain from the results, to me is, well, …priceless.
