Description from Mobygames:

County Fair is a shooting gallery game, in the tradition of amusement parks everywhere. Similar to Carnival, the player's gun can be recklessly waved left and right along the bottom of the screen; the objective: rack up as many points as you can by picking off the moving targets, until your bullets run out. Precision is a must, especially when aiming for the well-shielded trees at the back. If you take too long to get 'em all, the lesser targets will start respawning, so speed also counts.

Occasionally special targets will appear, which can either give you extra bullets, or take them away. Not all your targets are sitting ducks: surprisingly, the ducks are the most proactive - these beaked bullies will attempt to break formation and swoop down to gobble up your ammo(!). If you manage to clear the screen, you'll face off against the fabled end-of-round bonus duck, before proceeding to the next (and faster) level.
