About fifteteen years ago there were many articles explaining the economic advantage of double decking poultry and hogs in confinement facilities. Does anyone know if this is practised in the US? With all the talk of feeding chicken litter to cattle I wonder how many times the litter has been recycled. Also seems to me like some poultry and pork tastes like a confinement barn smells. Didn't really think about it until we had a neighbor's chicken for diner the other night and couldn't help but notice the clean fresh taste. Could this be why Walmart has to add flavoring solutions to it's chicken?
