I only use the Robo decoys in the late season Gary, when we have big flocks of migratory birds in. I use pigeon decoys I cut out of 1/2" plywood and painted flat gray with splotches of black and white. Used to shoot loads of pigeons and found that they work well for doves, especially the young birds in the early season. I neglected to take a picture of the 28 with yesterdays birds. Forgot the camera.
Yeah, 28's and birds(doves) go together like PBJ.
