On my Dairy farm once in a while we get a few deer here and there eat from our Silage bins in the winter but this year they are hitting it every night and more often than not its 10-20 deer at a time. Its high quality stuff with a mixture of Alfalfa, clover and corn so I see why they eat it. We have had to try and block it off with round bales and loaders but they still find a way in or just eat the round bales.
