I use them a couple times of year around rut. I've used 1 doe, buck and doe, and just 1 buck. I actually killed my first buck With a bow using a buck decoy. Shot over it's back at 25 , It ran about 50 yards across the field , I grunted a couple times And it came back ready to kick the decoys butt. Killed em at 30. Does seem very skittish around them. But bucks like to check them out.
