Hi there. I have 3 grown Pekin ducks. 6 duckling Pekin and 2 mallard ducklings. All are free range. The adults attack my ducklings. The ducklings outgrew they brooder box I had and I had to let them free range. They’ve done well for several days now. Until today. Today one of the adults was trying to what looked like drown one of the ducklings. The duckling is tore up because of it too. Obviously on land I can intervene. But when they’re out in the water there isn’t much of anything I can do. What can I use to get the adult ducks off of the baby ones if they’re behind my physical reach? Someone else suggested using a regular BB gun to scare it but I don’t wish to harm any of them at all. I don’t own animals of any kind for any other reason outside of wanting to care for them and raise them up. We don’t even eat the ducks we raise.
