What to do with hay?

we have just had a small field topped off, and oh has raked the hay into a small stack. But what can we do with it? No-one wants it for horses/sheep/hamsters. I have suggested he just lets it decompose slowly, but it seems such a waste.

 

Try advertising it locally, I'm sure somebody will claim it.

 

Being a horse owner for over 40 years I know a fair bit about Hay. Your Hay to be brutally honest isn't worth baling as will either have set seed by now on well on the way to doing so.This will mean the feed quality /goodness is not a lot and horses are extremely fussy feeders. Likewise Sheep will dig deep into snow to get grass rather than eat poor quality Hay. We often have baled Hay burnt as not of good enough quality to be fed. We don't always know it's poor, animals let us know!
Unfortunately, I think your idea is the right 1. Better if you can cover the stack post rain, it will decompose quicker and you can then use it to fertilize your flower/veg beds.
