I was in a wheat field this week ( its about 3 weeks from ripe) and the rooks had knocked down a patch in the centre, which was being attacked by both rooks and pigeon. I tried to decoy from the field edge but the birds were coming in about 70 metre's out. After numerous long range shots and only two birds in the bag (can't remember the number of shots ) I decided to set up the hide in the patch of broken wheat in the centre. I made the hide into a 1m square box which stood out like a sore thumb in the 1m high stalks, and thought I would have no chance but it worked like a dream until the heavens opened.
