When they are feathered, and warm outside, not breezy (they dont have the oils to protect them since they have no duck mom) the oils will come later, so avoid the water hole til they get the waterproofing oils, BUT get a 6 foot plastic kiddie pool, $12bucks at KMART, they will love it!!! And they will be having a blast outside. And yes they grow quickly, and did I mention the pounds and pounds of used duck feed? I had `12 peking ducklings in my garage, and it has been a while but I still have plaster stuck on the floor. Over a year ago... Pekings arent the smartest animals either so you have to keep watch over them. Had one walk into a pipe and STOP, it was open at both ends but it panic'd. HAVE FUN remember they are outside animals, not house pets. They require sunlight wind and grass. bugs, and water...
