Just give your mare time. Before you know it
she will have figured out how to eat so well that you have to buy the plug to
put in the bottom to keep her from getting too much grass.
My mare has been using one every day since the
grasses started coming up. I swear she blows up just smelling the
grass. I did just purchase the plug and she has already figured out how to
get some grass into the sides of the muzzle.
They really are a great tool just hang in there -
she will not starve but will probably always pout!
