I don't think that it makes any difference if the snakes a Lucy or not as far as husbandry goes. And like most American rats Texas rat snakes are pretty much bullet proof. They have a high metabolism so over feeding isn't really a concern. Mine has been used as a garbage can for unwanted feeders for years and even gets medium rats on occasion without becoming obese. They do fine at room temperature or even at 80+ degrees. Pretty much being chomped on is the only worry I can think of that these snakes pose for a keeper lol.
