I use a Dave Smith Hen Decoy ONLY. The Dave Smith is a solid construction that the toms and jakes can climb on top of, hens wollop the decoy, and she just keeps here calm and takes the abuseLOL.
I tried using jake decoys and the jake deeks seemed to keep the other jakes/toms at bay.
I removed the jake from the equation and the toms would come right in.
Here is a picture of one of my 3 turkeys from last season with the Dave Smith Hen Decoy. Yes, I was using training wheels. I plan to leave the compound at home this year.
Another that 6 jakes were fighting over the hen and this one fell victim. Unfortunately, my camera batteries were dead, so this is the next morning (don't worry, he was on ice all night)
