Is it normal or what does it mean if male duck is grabbing 1 of the ducklings and throwing it around. Duckling is 2-3 weeks old. Mother duck doesn't do anything about it. Male duck did it twice then I stompped my foot and he stopped and the 2 duclings left. They were the only 2 that hatched out of 23 eggs. They free range in 1/3 acre lot but I think male can still catch them.
