A friend gifted me with a bale of hay thinking I could use it in my nests. I accepted it knowing that hay isn’t straw. So, now I am wondering if I dare find a use for it. I know it’s full of seeds so I don’t want it germinating in my garden as mulch. Whereas straw is hollow and holds warmth, hay is solid and holds moisture. It cans go moldy. And if I understand correctly if eaten it can cause crop impact ion. The flock might like nibbling the seeds though. So, what can I safely use this hay for?
