Deer bed down to chew their cuds after they are finished feeding .. same as cows. When they bed, especially early in the season, depends on when they eat. Early in the season the moon/feed tables can predict when they will be up and around ... sort of. Later in the season, after hunting pressure, rutting activity, and weather fronts increase, it's much less predictable.
Use the feed tables as a starting point in your area and then you can change as you notice variations in the deer's patterns.
