Deer don' t care. I just got my turkey, let my 9 year old son call him in (actually he called in the whole flock!) and on the way out we heard more calling and he wanted to see if he could call another in... so I put down the turkey and my unloaded gun and he went to work, calling almost continuously... in about 5 minutes I heard something coming behind us, it was a 6 point and coming right towards us. He got within 5 feet of us before he noticed us. I think that turkey calls may even relax the deer, you know like the deer thinks " If there' s a turkey over there, it must be safe."
