I don’t think I need one, but is he correct and, if so, where should I place it in relation to the decoy pattern?

I thought rotaries came into their own when pigeons had difficulty spotting decoys in growing crops?

You are quite right, provided flighting pigeons can see your layout, they should respond positively.

However, there is no doubt that the added movement a rotary machine provides, seems to get the birds in quicker.

Be sure to place it well upwind of the landing area you have created within your pattern, so that decoying birds are not distracted in their final approach.
