I think I have found something they should NOT eat - at least in the winter. My ducks have been having a party in the Jerusalem Artichoke bed. Digging, nibbling, etc. I found the drake on his back, pedaling. the ducks were all digging, quacking excitedly. Were they high? Scared me! I covered as much of the bed as I could with chain link fence and gave them Vit C and Brewer's Yeast in their water for days. Anybody ever heard of this?
