They do sell duck but you should you be looking for a whole duck, you should call therm.
Yes, the Stoltzfuss poultry Farm has a booth in the market, and they sell fresh whole ducks, capon, goose, and rabbit. If I remember correctly, I might even have seen duck breast in their display? Their assortment can vary, and I recommend to give them a call upfront. They also accept preorders by phone (no prepayment necessary). Their number can be found on the Farmers Market's home page under 'contact us'.
