In most states pigeons are not considered game animals and are the shooting is totally unregulated. You can bait them, make decoys of folded cardboard with a little grey and white paint. Make yourself a flapper or two with glossy white wings to flutter to attract their attention if flying nearby. And have a few wire frames from hangers that you can use to prop up the first birds shot as additional decoys. Most dairy farmers would be glad to have a responsible type shooter work over their pigeons out away from the cattle. Just don't over educate a particular flock by shooting it up too frequently. If they are decoying in 7 1/2 shot works okay but if you want to pass shoot some taller shots go to 6s.
