My corn spent a night and half a day with the live pinky, and it didn't even strike, I'm assuming since the pinky was still alive when I took the snake out of the deli cup this morning. When do we "pull the plug" so to speak? The corn hasn't eaten since it hatched, apparently. I don't want to starve the little guy to death. We have tried EVERYTHING. Is there a step that doesn't involve the freezer?
