Gamey as in stinky from being thawed and left out and starting to decompose, I would think.

As far as the shed, there's no need to soak or use sprays. A healthy snake kept properly will shed just fine without being messed about with. Keep the soaking for when there is a problem with the shed. We have two stickies here...one about the shedding process...one about what to do about bad sheds...both are well worth reading.
