Containing our pig

Question
What is the best way to contain our pig.  She has a large fenced area but gets out a new way everyday.  We have bricks under the fence, chain on the gate, etc. but she is so strong, she breaks through the fencing.  How do most people keep their pig penned and safe?

Answer
Hog or cattle panel fencing sunk 6 - 12" below the surface, with chain locks and steel fence posts is the only real choice for containing large farm pigs. Smaller pot-bellied pigs might be able to slip through the larger holes (especially in cattle panel), but chicken wire or mesh attached to the fence with a twist wire ever 12" or so will keep the pigs from pushing through the holes.

Most pigs are easily confined with ordinary wood (or the new plastic) privacy fencing, with chicken wire at the bottom sunk a foot or so into the ground to keep them from rooting under it. When I lived in the suburbs, my male pot-bellied pig never escaped from the ordinary 4' chain link fence that surrounded my back yard.

Blizzard or snow drift fence (the wood fencing used in snowy climates to control the height and location of snow drifts) and decorative picket fences are not strong enough to confine a pig. The plastic mesh used to keep wild animals out of a garden is useless for confining a pig, unless it is fastened to hog or cattle panel. Chicken wire or mesh is also too weak to be used alone, but will keep most pigs from rooting under a sturdy fence.

Hog panel might be harder to find in suburban or urban areas, but even when wrapped with chicken wire it's usually cheaper than privacy or chain link fence, and installation is much easier.

I am assuming that your pig is a female, and that she is not spayed. Unspayed females are talented jailbreakers, their hormones drive them to seek out mates. Spaying turns restless sows into happy, stay-at-home piggies.
