These are some great questions! While you are in some "down" time with your snake, I would get a couple of books on corns (two of the best were written by two of our members, Kathy Love and Don Soderberg, I would order them from Amazon or their websites (to get them autographed!) and also read all the stickies at the tops of each subject.
And read as many posts as you can, I guarantee you will answer questions you didn't even know you had!
Good luck, and we are always here if you don't find what you are looking for.
