so if they get rained on does it ruin them for feed?
i ain't no farmer for damn sure.
Round bails are more weather resistant than square bails. If they are rolled tight enough the rain will shed off just the the top of a well rounded hay stack. If they are not tight, and the top sags, will, that's a different matter.
Of course many of today's farmers and ranchers are an aging population. This might not be the result of a plan, but the result of hardship.
