Is this normal? My boy duck will hike around the pen picking up poop (his or his sisters) and chowing down. He always waits till its hard and dried out, then picks them up and eats them like triscuits. It grosses me out. They are fed fresh food/water 2x a day. I fill the water tray half with food, and let it fill the other half with water, so one side has mostly water (some of the food disolves into it), and the other side has moist food. I do this because when its only water, they obsess over it (they will drink a ltr in 2 hrs with out food) and wont eat at all. Is this normal duck behavior? Something I shouldnt worry about? I dont want him getting sick, but he seems to prefer the poop cookies more then his normal food. By the way he is 1 week old.
