I always enjoy your pictures, Soapweed.  What percent of your hay do you figure your cattle waste the way you feed it?  How often do you put hay out?  I am trying to reduce the amount of waste I have ( especially this year as we are all short of hay down here).  I both unroll it and feed in rings and I can't say either is less wasteful for me.  But when I unroll it I can better control consumption.
