deer will eat it, BUT IMO the problem comes down to how do you keep it from going bad
as all things like this once wet if not enough air flow is ALL around it, will get moldy and them your wasting your time and money and deer shouldn;t eat it, being MOLDY unless there VERY hungry and then it can make them sick
just the block or cubes LAYING on the ground will absorb moisture and that will turn to mold
yrs BACK I used to use BIG bales and used a chain saw to cut small sections off them and had a rack that held things off the ground and a small roof to keep rain off and it dry
deer sure ate SOME of it, but more went bad on me and went to waste, I mostly ONLY did this on extremely hard winters to MAYBE help and or maybe help me find sheds>
and it still didn;t get used much? or as much as I had hoped it might! and wasn't worth the costs or work to put out and get rid of moldy sections(would pull out and burn)
same experience as I had with using the blocks that are compressed together, yes some deer will eat it and come to it, but not a huge draw where I have tried them
honestly the best thing to do if possible is PLANT food that lasts into winter
standing corn is HARD to beat as it doesn';t go bad, offers cover and wind protection, cheap seed can be had thru discount programs, or some decent timbering that makes good natural browse or planting good browse
have to remember there is NO fast fix, good things take time and effort IMO
we don't all own land, but most can improve what and where they hunt some?
