Ah ha!  Now we're getting somewhere.  You don't have a phobia about chickens at all - it's bow ties that you fear.  Well, you'll be pleased to know that a fear of bow ties is not unnatural at all.  Bow ties are actually a species of snake from Malaysia, which are specially selected for their suppleness and rich coloration.  They are rendered unconscious with a cocktail of drugs and a succession of heavy blows, then shipped out to adorn the necks of dapper gentlemen all over the world.

Unfortunately, they have a tendency to wake up and throttle their owners, which is why many doctors like myself have been actively pressing to get them banned.  You are right to fear the bow tie, for it is an evil thing that should be shunned and hounded from our streets.  Go now, little one, and spread the word so that all the nations of the earth can live in harmony, free from strangulation and neck-peril.
