We got chickens because my daughter has GI problems. The doctors can't find a "medical" reason for it and allergy/elimination testing has done nothing. Her latest GI dr thinks she may be allergic to a preservative. So for the past 5yrs I have been buying flour in 20lb bags and making everything I can. Bread, butter, buttermilk, pancake/waffle mix, hot cocoa, syrups... Anything I can find a good recipe for. So for us raising our own for eggs and meat makes sense. With local feed prices and store chickens it comes out about the same.
If I had the space I'd have a steer and hog too. We have rabbits for 4-H but I've never butchered a rabbit so I'm not sure how to do it. I guess I'll bumble through it this fall.
