Well, that was a quick change!  Goodbye pasture!  Haynets provide a great way to extend feeding times, keeping the gut happy.  The horses will still eat the same amount, just over a longer period of time.  Similar to grazing.  It also saves on waste, therefore money!  My older mare never drinks enough at this time of year, so I soak her hay in warm water and then hang it overnight in a warm stall so it doesn’t freeze.
