Soak the actual snake in chicken broth??? Good lord now I have heard it all!
If this is an accepted way to get a snake eating I've totally missed that one! LOL I have heard of dipping an f/t rodent in chicken broth, though I've never tried it myself but soaking the snake itself in broth.....
I've learned to smile politely and move away quickly from most of those sorts of pet store instant experts. Unless I'm pretty sure it's an employee with real experience or I'm in a specialty reptile store, I tend to not take their advice.
