All of these answers about pens-within-pens are a bit far-fetched...

Here's my solution:

1.) you take 7 pigs, and place them in pen #1.
2.) Herd 5 more of the pigs into pen #2.
3.) Chase frantically after 3 pigs (it's getting harder to catch
    them now), and when you get them, put them in pen #3
4.) Slowly, methodically, lead each of the remaining pigs
    into pen #4. (Save the pregnant one for last...)

This leaves you with 7, 5, 3, and 9 (three adorable piglets
were born the instant ma was led through the gate).

Papa pig will be distributing cigars from pen #2...
