I baled some like that last year, left them sit all on their own far away from anything. For months.
I fed them, free choice, last winter, there was a lot of waste, but the cattle got something out of them.
Be careful, they might turn out ok and they might start on fire, all depends.
If you are feeding hay, you can use a few up quick - be careful on messing up the cattle, but as part of the free choice, they can work over a few bales in the next week.
