As far as round bales scattered around a field, multitude of reasons from not enough time to no storage to too lazy. FWIW, round bales left out in the elements here in KY lose up to 3" to 4" of outer layer due to rot from rain and snow. 3" to 4" on a 48" roll may not seem like a lot. But, I'm told it amounts to 25% to 30% of the hay volume in a soft center roll. Stacking them in a pyramid pile outside just exacerbates the rot.
Many folks in our area are building the hoop frame fabric barns/shelters for storing hay rolls out of the weather. Son In Law has put up two of them. He says the only thing better are the silage wrap bales.
