Warning: I am NOT AN EXPERT!
I am new to snakes. We got a King (Florida Brooksi) earlier this year and added a corn a month or so ago. Both from the same breeder/dealer.
Anyway, he told us when we got the King to handle her pretty often, and when we do, to touch her head. She flinches at first, but then settles down. Supposedly this is to help them not be afraid to be touched on the head when they get bigger.
Regardless, this King is now almost 30 inches long, and is SUCH a sweetheart! Could not ask for a better temperament. And I handle her pretty often. I could have gotten lucky, but the corn we got was bigger than a baby and didn't seem to have been handled as much, and he is WAY more skiddish than the King.
