has anyone tried these, went and bought a box the other week, so got to try them on saturday tere seemed to turn birds away. had a few pigeons and mixed them through. had to go up to the van for something and looked back could hardly tell them apart. so i brought them home and put them in the garden to see, had a few look but nothing even thought of landing. i bought a few them flocked crows on tuesday and tried them today. night & day difference so il puting the fuds back of the shed and getting a few more flock decoys. anyone else had similar experience?
