I live in the Northeast- which of course means snow, and soon! I am moving my duck run from the grass to under my deck for the winter. The ground under my deck is brick patio and when attempting to tuck my ducks in last night they seemed awfully upset that there was no grass. Do you suppose winter rye grass will work if I pull up the bricks? I could just lay straw but that could get costly/ messy over a period of 4 months or so.
