Thanks everyone!
Incidentally, my Bullsnake is a several generation captive born snake. I do not believe in taking snakes from the wild as pets. Although some may fare well, others will not. Also, in some States, such as Iowa, it is illegal to catch and keep Bullsnakes -- (video on link also):

In Kansas: (calling it a Gopher Snake but this is a Bullsnake):

I wish we had them in Alabama as well. Our Pine Snake is a very secretive animal and very, very rare to discover one. In Alabama, Indigo snakes, if they still exist, are illegal to possess (as they are in Florida). You can buy & own them that are captive born however (and there are plenty of herp breeders out there rasing these snakes).
Like many of you, we have Rat Snakes in great abundance. They will take young chickens and eggs before they will eat rats or mice (though my big birds will kill even a large rat snake), and I try and relocate them afar anyway.
HippieChickens:Is it just puffed up, or does it have a full belly?
She is puffed up but she eats 1-3 rats per week so stays full.
Sitka:Any clue why they are called Bullsnakes?
I don't have any idea why they are called Bullsnakes. I looked in the literature for the answer to this question and have not found anything. The Genus is Pituophis (pronounced PIT-CHEW-O-FUSS). The other members of this genus are easier: the Pine snakes which I know are found in pine woods and Gopher snakes because a favorite food is gopher rats. Bullsnake is Pituophis catenifer sayi.
My Buckeyes are excellent at catching mice as well; thank goodness, they don't eat as many as the Bullsnake though. I had a 12 week old cockerel catch a mouse a few weeks ago. This is the youngest Buckeye I have seen catch a mouse. I was out doing early morning chicken chores and noticed the young cockerel move at lightening speed and come up with the mouse. The other juveniles chased him for it.
