My brother has horses and buys over 400 bales a year for winter feed - he gives me the greenest 2nd cut bales for my geese and ducks. I have 6 Geese and 20 Muscovys eating the hay free choice and because we have snow covering all the winter rye I planted in the fall, they are going through the completed bale in a week. They get complete commercial feed , but seem to love the hay.
