At our local coffee shop I heard a guy tell how when the ground gets covered with snow he puts out a few bails of hay for them and said they eat it right up. Then another guys chimes in and said that deer can not digest dry hay and that it takes more energy to try and digest then they get out of it so if you feed it to deer you can do more harm then good. He said they do not have the enzymes to digest dry hay, but when it is green the enzymes are in it. Anyone else ever here this?
