Being a fox in a hen house is often a cliché, but in this game - it's the way things are. The fox needs eggs, so use the arrow keys to move the fox around and catch the eggs as they fall from the chicken's nest. Foxes don't like rotten eggs though, so avoid those at all costs. Those eggs will cost the fox a life, and there are only so many of them. The levels get harder and harder so practice your hand-eye coordination and get all the eggs you can.
