Way to go Garry. I do not recall ever having a bird thrashed that I had taken with a gun although it may have. Archery killed birds are another story as I have had that happen numerous times. They will hang in there for the most part and abuse the downed bird about as long as you can endure the show.
On another note I like to take the breast and cut it into chunks not to thick, say about 1/2" max. Cube it with a hand held cuber, marinate over night in Zesty Italian dressing, right out of the marinade into your favorite flour or breading and then cook over medium heat. Tender and yummy.
