You don't have enough - they love them where I live. Really, if the pecans are going to go to waste, put them out in one or two places once per week till they are gone. If the deer have never seen them before it might take some time for them to try them out, but if/when they do they will definitely come back for more. Don't crush all of them - crush a few dozen in each location to stimulate curiosity and a taste test. They won't need any help after that!
