Just a note here on chicken. It cost me $6.00 to raise meat birds to slaughter including the cost of the bird. They were allowed to free range during this time as well. The chickens were butchered at the 4.5 to 6.5 lb range.
The dark meat turned out nearly as white as the breast. Without scientific equipment to test I'm still assuming that they are leaner than store bought. Labour aside they cost half the price as an equivalent store bought chicken.
Free range chicken eggs are better for you as well. I think they were quoting 1/2 the chloresterol as store bought.
