Thanks guys! Yea a lady down the road picked him up. He rolled past her house in a wind gust. She kept him in a box on the lawn to see if his mama would come but she didn't. We don't have any water sources nearby so can't make a guess as to his home...
I knocked together a smaller brooder for him and he has a buddy and better food arriving on Friday. He is eating soaked and mashed pellets mixed with handrearing mix. He loves to splash in a bowl of water and gets to eat bits of green. We he is not following me he loves to snuggle his lion soft toy which is full of wheat so can be heated.
I've reared ducklings with chicks in the past . Ducks do tend to have a higher requirement of niacin than chooks, so if you aren't inclined to add multi Vits to their water, then it's a good idea to keep Brewers yeast in your first aid box.
