no mate no wind up put them out on small sticks just like pigeon deeks . put the chip tray deep end down ,so they move in the wind .we have also spread pieces of toilet role out around the flash works just as good night or moon no good during the day.if you dont have a widgeon caller make one with the brass heads from whinny and eley carts put one inside the other get a good snug fit dont forget to take out the primers then tap where the primers have been with a punch till you get the right call. we have been doing this for years no joke .
