Can you say 100 acres of clover, cattails, dandelions, grass, trilliums, orpine, bee balm, and strawberries? (all of these things are potential menu items for the ducks... I'll have to observe them more this coming spring)
It has worked for 6,000 years in the wild, so I figured it would work for me. To tell you the truth though, I really don't know what all they eat. I just know that they find it. Dandelions and clovers are plants that I've seen them eating, but the probably eat other things.
And it's day-old...
