Sounds like you might have hit a bit low through the breast w/o any vitals. Both birds I've gotten with the bow went right down, one was trying to fly but had a broken wing to go with his internal injuries and the other had a broken hip and wing and basically fell on his face after the shot. Both shots were pass thru so I wouldn't have worried about having too much energy.
How close did you get for your shot? Just curious, no bashing planned. 
Good luck getting on them again.
i think you may be right on where i hit.i was leading him due to him walking in.it was 30 yards on the dot when he walked in.i had my decoys at 20 yards n i think he would have come all the way to them,but i fealt really good of the shot.
i play it over and over in my head.i dont think i needed to lead him at all,i think i coulda waited 60 more seconds n made a 25 yard shot or 20.idk i know i am screwin up,and i appreciate all of your advice.
they have fled my property for the time being.i could not get a peep out of em last night.
