Any tips for helping ducks with anxiety?
We have bad neighbours who are always yelling and screaming and fighting and unfortunately the pond where our ducks live, on our property, borders on the bad neighbours.

The neighbours had settled down for a couple of weeks in July and actually went away for a while. It was peaceful and beautiful while they were gone but unfortunately they're back now and back to fighting, yelling, screaming, etc. It's awful and after the peaceful interlude my ducks are traumatized by the end of the day listening to them. At night, instead of going home at bedtime, they're panicking, running around, quacking, and totally in fight/flight mode. I end up carrying them into their coop, one by one.
I have seen the police @ the bad neighbours place a couple of times this summer, and i don't really want to be calling them or bylaw over every little thing, because if something big happens, i want them to respond right away and not say, "oh it's just that lady who complains about all the little things all the time". And we also have to live beside them, and i don't want to deal with any kind of retaliation from them. They're just horrible and i don't want to antagonize them.
I was thinking about putting a white noise machine in the duck's enclosure to see if that helps muffle the sound of the constant battle sounds coming from next door.
When we lived in town, our dog had a lot of anxiety and i gave him passionflower tincture, which really helped. Can Ducks have passionflower?
Any other ideas?
Also, we only have an acre, which seemed really big when we bought it, but there's nowhere on the property where we can't hear the neighbours when they're yelling, so moving the ducks to another spot probably wouldn't help anyways. I was awake last night past 3 am worrying about all of this and trying to figure out what to do about it. i also have chickens who stop laying because of the noise, my rabbit had her last litter on the wire on the wrong day and i'm sure it was directly because of the neighbours, i don't let my kids outside when the fighting is going on so they've been inside wayy too much this summer, i try to plan my outside projects for early morning and late evening when it's quieter, etc etc, etc. it's had a huge, negative, impact on our quality of life.

Not sure if there's really any good solution to any of this, other than moving away, but we can't afford that right now. I can see why the previous owners of our property sold.
