Billie, check behind the flowers. The ones with a miniature fruit are female. You can use pollen from the others. If all the flower stems are straight, you have male flowers only. That seems to happen when the weather is a bit cool as the plants start flowering.

Billie, and Bridget, your zucchini are dropping off because they are not pollinated. You can help pollination with a soft paintbrush if there are not many insects around.

Lisa, zucchini/courgettes behave like that when they are not fertilised. You could try using a soft paintbrush to do it by hand.
