Smallholders have been raising pigs 'without' the stink for generations, especially small sucker pigs that do not shit too much and have decent drainage.
My point being.... if animals are kept in reasonable conditions that allow for their habits, ie, pigs are grazers, sheep are grazers too, chickens need an outdoor area. If you do the right thing by the animals and not cage them. Most of the domestic stock we seek or need are very easy to deal with.
Pigs dont stink.... pigfarms do, rabbit farms do, cat farms, minx farms and so do chicken farms, hospitals and dog farms... you get the point. Even people dont stink when they are compressed into nasty situations that they cannot move from...
So bring on moveable pens, it works for most of God's lil creatures and especially... GET A PIG.
They are just the best and remarkably responsive..
