Chicken represents what you need or desire in your life.
Fox refers to foreign invasion.
If you feel anxious to get rid of the fox when you see it coming, you are inexplicably extremely nervous, which shows that although you have some confidence in foreign invasion, you are still a little timid. Then you should be confident and believe that your ability can overcome those external troubles. If you don't feel nervous, or even have the pleasure of chasing foxes, it means that you are slightly satisfied with your current living conditions and hope to show your extraordinary ability one day.
