Glad you got som large ones to stuff. The little ones that turned yellow and fell off were not fully pollinated. This season, plants marigolds, nasturiums and other flowers pollinators love among the zucchini. They'll draw the insects to the flowers and pollinate them. You can also use a a watercolor paintbrush to hand pollinate the flowers after they open.
