I have 6 pekins who are about 6 weeks old. I still have them on the started feed and they free range for about 4 hours a day and munch on greens. Every morning and before bedtime I fill their 7lb feeder up about 3/4 of the way and they seem to scarf it all down and still want MORE! So I it's about 2lbs of feed per duck a day. During the day they will come up to the back door and quack and quack for more food. Am I not feeding them enough or are they just being little piggy ducks?
