I grew some round courgettes a few years ago; a Marshall's trial if I
recall. I found they soon got tough with thick skin, hollow centre
full of seeds and not much flesh, so pick them young would be my
advice, then the plant can go on cropping.

Whereas last year I grew "One-Ball", and found it to be highly
productive, and tasty and wonderfully tender at any size. The largest
ones, around 6" diameter, we baked with stew in the middle like
pumpkins, which was delicious too.

I'm growing one called 8-ball which iirc was recommended for eating at
golf-ball size..the first will be ready in a day or two.

To the OP ,you don't need to thin out courgette fruits, and it might
have the unwanted effect of amking the survivors grow big faster.
Courgettes are so delicious young and tender (and much tastier than shop
ones).
