Ya pile em in the field and build around them of course.
S had an idea that may work.
Build a pvc pipe structure and cover it with silage plastic.
Before you ask me...
Yes that's a fake cow there.
It's used to practice roping. It turns in a wide circle on a moter so you can ride behind it on your horse. Once it's roped and pulled snug it stops for you to get your rope back and then restarts to keep going.
Back to hay....
There is a learning curve and potential issues involved.
It will sweat inside which we do not want as it will cause bales to spoil. We did fold excess back on itself and tied it down. It was too dark for a picture when finished. We left enough hanging that can be closed over the ends during storms but re opened and pinned back during good weather. Hopefully air/wind can blow through preventing or minimizing mold or rot on bales. There is a bit of room down the sides but not a lot. We will see if this works today as thunderboomers and rain is crashing through and expected for next 24 hours. That is much needed rain so we are not complaining.
We have a lot of wind at our place so I'm leary of the durability to withstand that. S had a dream so we shall see.
His idea is as we deliver them about 5/6 at a time we can remove sections and fold back plastic to shorten tunnel. Eventually removing and storing it for next year if this works.
We have another 40 bales stored under the loafing shed to use after these. The customer who contracts for them has mini horses and show stock. We have run out last few years so we are hoping this lasts awhile longer.
