Unless you've got drainage problems and need to raise the level of the ground I see no point to adding sand when you've already got the start of a Deep Litter System going with the wood chips.
Better to mix the wood chips with shavings, straw, last fall's leaves, and other "compost browns" that will absorb and break down the poop. Sand just collects the poop then stinks when it gets wet.
