Here is what I've been seeing the past few days: ducks will march all over the yard stopping to dibble any exposed grass patches. They were messing around with (eating?) the branches of our old christmas tree, they are exploring the dried leaves of any plants left outside. They seem very restless like they are looking for something specific and this morning didn't even stop to look at the fresh water and fermented food, just took off into the property doing the above. I gave them some green peas which they gobbled up, which is not unusual. I put some fermented feed and some dry feed closer to the house where they've been congregating but they didn't do more that look at it. I couldn't shake the feeling that they wanted something to eat that they aren't getting so I chopped up some lettuce and they really gobbled that up. Then they walked back to their pen area, ate some fermented food and drank some water and now they are calmly cleaning their feathers and have stopped the marching around business. So. Are they starving for greens and do I need to provide some to them every day? I feel bad if this is what they wanted, poor things. It's only been a couple of days that I've seen this behavior, though. We're up in Wisconsin, everything is frozen and snow covered including my ducks beloved river Does anyone have an insight on this behavior and what I'm doing wrong?
