Welcome to NGA,
@GardenerSuz !
I agree with Kat -- it would be helpful to know where you are located. (My gardening season is nearly over, unfortunately...
)
If you are in the far south, and your weather has been quite hot, that could be inhibiting the formation of squash. And, as Rita said, be careful not to give too much nitrogen fertilizer to the plants.
I doubt there is anything wrong with the zucchini seeds -- but some varieties are definitely more productive than others.
