I got ducks yesterday, and was told they would be hungry because they missed breakfast. I have put food in for them but I haven't noticed any of it being gone. They are skittish and prefer to be away from me, and are in a dog kennel until the privacy fence is finished... it has taken longer than expected. They are playing in the water, drinking etc. I have put regular food, lettuce, and even tomatoes in and haven't seen them eat yet.
