I've got some late brassicas that really desperately need to go out.
If I put them out now, presumably I won't have much of an issue with
butterflies, but will I still need to net to stop the pigeons?


Yes a net is pretty essential. Our allotment is plagued by them.

I've got a cage. made from old trampolene netting.

A rectangle of net on a wooden frame with sides hung down.
6 poles (ex-gazebo short ones) which catch the screws on the wooden
frame and it all sits nicely.
The sides are just hanging down but clipped at the poles on the
corners with those mega-clips you have for market stalls.
