I've noticed it with my 9 ducks. One boy and one girl are 4 weeks older then the rest. The flock is 3 and 4 months old. The 2 older ones seem to be in charge of the whole flock. First there is the usual discussion of quacking around. Then the boy starts to walk and all the younger girls usually follow him almost blindly. Last is the older girl making sure they follow him. Non obedience will be followed by her bobbing her head and nipping feathers and tails. This will go as far as wing biting if there is one that still doesn't want to listen (does not happen very often at all). The older girl has a real grip on the situation and the rest knows not to mess with her. Its really funny to watch, but big boy is not always that helpful. Usually he know what we want him to do, but occasionally he gets hard headed and tries it his way. Telling him that he will get peas usually sets him right. He is a beggar and know the word really well.
