Yes that myth is busted!!Turkeys fly over water rivers etc.
I even called them down a ridge,If u ever heard that tale that turkeys wont come down hill?But Ive noticed over the yrs.Like was stated,Its competition,When there are more then one turkey coming,Its least likely when its a single turkey.They do just about anything there not suppose to,When theres more then one.Just to be the 1st one there!!
