Cattle, goats, pigs, dogs and yes even chickens can go 'wild and dangerous' in Texas if the conditions are right. They can be a dangerous threat to any unsuspecting individual who has been raised in the urban atmosphere and led to believe that these species are harmless. I live in West Texas where even humans go wild.
I saw a ferel bantam rooster kill a jackrabit not long ago. Horny bast*rd...
...Jealous tourist.
Later that night, from the trail boss to the cook: "There's feathers on your zipper, pardner. Did you bone this chicken?"
