some how I replyed this, but it never took I guess
when you feed cubes or any alfalfa , you have to remember that if it gets wet, it will get moldy very fast, and mold can make things that eat it sick or even kill them
sure corn will get moldy too, but takes longer, and normally doesn't last that long
if you feed alfalfa , try putting out small amounts till they start on it
when i feed the Big bales, I place them on a pallet so they can get air on them on all sides, or better yet cut them in smaller pieces and put out that way, still keeping them on a pallet with a tarp over them, till I need more
