Green food is very necessary for stock ducks.

Where they have a pond it is a good thing to throw grass cut up short into the water, it keeps much longer than if thrown on the ground. It must be cut short; if not, it is apt to block the passage leading into the gizzard. When it is thrown into the water, and the ducks do not happen to eat it all up at once, it keeps nice and green, and they appear to enjoy it so much more when they skim it off the top of the pond.
