Something is eating my Raspberries

I've noticed a lone turkey in the field below our barn several times in the past weeks and now I know why, its been eating my raspberries. I've seen the turkey near the barn and garden several times before and thought the bird was just passing through the area to get to the corn field behind the barn. As I waited at the barn with my camera ready to get a photo as the bird passed I noticed the bird head directly to the raspberry patch in my garden. I have an electric fence around the garden to keep the deer out, but it doesn't keep turkeys out.
