Cauliflowers have been eaten

Hiya, We had a break in by a bunch of rabbits  who have eaten my cauli's. Almost all of them have a couple of tiny leaves left in the centre of the plant so I am thinking that if I leave them they might spring back from the brink.

Am I just being hopeful, should I pull them up chuck 'em on the compost heap and buy some from the local nursery, OR, should i secure the netting and give them plenty of love and keep my fingers crossed?

Any advice would be welcomed as I have never grown cauli's before.

thanks in advance.
