Hi, I am kind of devastated and disgusted. Rarely have I seen something beyond my comprehension. I saw two kids (around 7 and 13) throwing rocks at a river (ironically where my ducks spent), I looked at them, they noticed me and ran. A few seconds later, my female mallard swims up and start quacking like there is no tomorrow. I try to look for the other two because they are always together. I find them on the grass on my neighbors' property. Both males are limping. One of them can barely walk, what hurts me the most was that when I come close, (usually they give me a friendly quack), instead one of them tried to run away. It couldn't. It flapped wings on the grass, but I caught up with it. I picked it up, it struggled so hard (I never seen it struggle so hard), but I got it back. The worst part about it was that they were smiling and throwing the rocks with all their strength and I saw everything. To be fair, it is kind of my fault since I should have kept them on near my home. They are mallards so they wonder around a lot and everyone lives pretty closely. I want to talk to their parents about this, but my parents discourages it. They believe they will just deny it outright and say that the ducks should never have been near their property anyways. Everything feels so wrong and I don't know how to deal with this. The event itself is beyond my understanding why someone would harm a defenseless creature that hasn't done anything wrong, but more importantly, I don't know if I should just keep them locked up until I get home. Advice or prior experiences on such events would help a lot. Thank you.
