Vic has made the comment that we seem to go through hay faster than anyone he knows, given the number of horses we've got this winter.
That would be because as soon as the horses move out of the paddock with the round bale, the deer move in.
They nibble. They curl up and nap in the loose hay. They nibble some more.
This pair greeted me this morning as I opened up the barn to let the horses out. They were enjoying breakfast!
