Today when I came home from work I thought there was blood all over the ground in spots, I thought a hawk might have gotten a bird. upon further investagation I found it was berries from the Cranberry bush. They were laying on the ground all chewed up. What would do this? Are these berries the kind that birds would not like? They sure tried a lot of them before they decided the whole bush tasted the same. Any one else have this happen?
