On one hand I have my 9 adult ducks(well technically they're 7 weeks but almost full grown) that I rasied since they were itty bitty ducklings(Okay, I bought one of them as an adult, so I raised 8). On the other hand a group of ten ducklings all 2 weeks old. Well my older babies have been free ranging since week 3 and just today we decided to see how the new ducklings would do outside. They absolutely loved being outdoors and took to it really quick. But once the older ducks caught them at the watering pan they moved in and chased them away. I didn't see any of them biting the ducklings but they kept chasing them away, and even around the barn for a while. They did ccalm down after a while and lounged in separate groups in the yard especially after I put out a second pan of water. I'm just a little worried. Is this a territorial thing? Or a dominance thing? I had to go to work so my fiancee had to put the ducks to bed tonite and said that the ducks and the ducklings all put themselves away in the barn at sundown. The ducks do that normally I was just pleasently surprised to hear that the ducklings followed suit. I was informed that there wer no further incidents and we are planning to let both flocks roam the yard freely as long as it is safe and there are no injuries.
