You need pigs, chickens, and humans living under the same roof...literally. Crazy as that sounds, it was done in the poorest regions of china and south east asia...maybe it still is.
Yeah...and go to any rural area with large mex...immigrant populations and you find that.
Lot of absentee landlords hire Mexican farm managers and others.
You can find pigs, goats, ducks and chickens all living together right next to the family quarters.
