I happily forgot that pekins are MEAT ducks. But my hatched Rouens are keeping right with them. They clean 2 LBS. of feed and a gallon waterer (Most on floor of brooder I am sure.) in 1/2 day. Only time they like me is when 1 or other is empty. Have not lost any yet, just 1 hatchery Rouen with them was lost. Other 9 Rouens doing fine. Will move tomorrow to larger growing pen for space and outdoor access.
My 2 month old pekins are like that too - I'm a big scary thing, unless I'm holding food.
