Question 1: The ideal temp to allow venison to age is between freezing and about 40 deg. Anything above or below that and you're not doing yourself any favors. Personally, I process mine as soon as possible, (same day or the next,) especially if the weather is warm.

Question 2: I don't bait, but my friends that do bring some in every time they hunt it. If they're not hunting it, they stay out.
