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

By April, zucchinis and other members of the Cucurbit family (pumpkins, cucumbers, etc will be starting to die off. You may get a few more days that will ripen some of them but you are probably better to remove them and plant cabbage, cauliflower, etc or prepare the soil for broad beans. Check the page for your climate zone for other things to plant.
