decoying on rape

[shottyscotty 3]

i was out on saterday decoying a small rape field and took ten decoys half shell and half full body. i was set up right under a few big trees on the border of the field and found that the pigeons were landing right above me and looking at the decoys but not coming in apart from 2 witch landed and i hit 1 but didnt even see the second 1 come in untill it took off and was gone. I was wondering why if the birds wernt seeing me would they not come in and land and there was 1 other person decoying but they had no look either, any advice would be great. i was thinking maybe some movement might of helped but dont know any cheap way of doing it

movement is good if you have shell decoys try makeing the fitting peg looser so that a slight breeze moves them up and down any movement is good.
