If you have that many birds out there buckshot, those deer are used to them by now. If I were you, I'd hunt close to those birds as you can. Those deer are obviously at ease around them. That is one animal that deer don't mind being around. When I'm in the woods and I see turkey I always hope they'll stick around for awhile because if they are around, deer KNOW that everything is safe. I don't think there's an animal as skiddish as a turkey!
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
