John,
The good news is that there is a light at the end of the musking tunnel! My Kingsnake broke that habit pretty quickly (about 3 weeks to a month), but my Pueblan milksnake. . .wow. We adopted her from some people that were looking to get rid of her. She was hardly handled the first year and 1/2 of her life, and when she was handled the people were nervous about working with her. She was also neglected and parasite ridden. About month after her trip to the vet (and 2 doses of wormer later) she was healthy, but undersized. This is when is started working with her on a regular basis. I would gently handle her most every day unless she had just eaten or she was shedding. . .talk about getting crapped on. Because she is such a shy species and had such a rough "hatchling hood," it took her between 4-6 months to calm down, but this is a drastic case. Part of what made those months a little easier was using a towel. Find one you obivously don't want to use for anything else and hold the snake over it when you take him out. It also helped my snake if I sort of made a "nest" for her with the towel and let her crawl into the "nest" and hide pretty much as soon as I took her out of the tank. Then I'd let her chill in her towel for a minute. Needless to say that towel was bleached more times than I can count, but I noticed when I reached back into her "nest" to get her out she was more calm. The towel is also a great way to wipe the musk off you and your snake. It's even better to have an old tupperware container to make the "towel nest" in.She never musks on me or my husband anymore. And I'm happy to say she's healthy and has grown to the average size of a 2 year old pueblan milksnake. I know I'm longwinded, but I hope this helps. It sounds like you have a beautiful animal. Good luck!
