My neighbor came over and excitedly explained that one of my 9 month old hens had caught a snake. So I went to investigate. She had caught a gardner snake of about 16 inches in length and was thrashing it about. After about 3 minutes she had it killed enough to eat and I thought she would tear off small pieces but no... she swallowed the thing whole! I'm proud of her... I don't kill gardner snakes because they are helpful but if one is caught by a chicken it is a free meal.
