Some of our Brit friends & members should be able to help you by sharing their prefered methods and hides and a source for some shell decoys commonly used for decoying wood pigeons. I am not aware of anyone selling them here, tho their may well be sources I am not aware of.
In South America, decoys are also used tho they are a bit different, often simply stuck on a pole in expected areas of flight and any and all birds taken are utilized immediately by placement either on another pole or in the crotch of a branch or simply placed on the ground to further enhance the 'spread'.
On thing about shooting pigeons in the field is to learn to disregard everything your brain is telling you about the birds' speed and the requisite amount of lead. Rather, take that data and double it. You will then get results.
