I don't think they have spawned. We fished Fri/Sat last week for smallmouth and never caught one crappie, and most of the places we caught smallies were banks we usually fish for crappie as well. We were throwing jerkbaits and typically that catches quite a few crappie when they're shallow. We never found any water above 49 degrees, but the warmer weather I'm sure has got it going in the right direction.
