0 ParaLogic Posted May 14, 2013 Report Share Posted May 14, 2013 You could construct three small, separate, pens with three pigs each. Then you could build a fourth pen that surrounds all three of those pens. The outermost pen thus contains 9 pigs (an odd number). Quote Link to comment Share on other sites More sharing options...
