hey there @buff goose guy !
I've heard of people buying these types of lights that look like red glistening of animal eyes and placing them in areas around their coop/run. You have to move them periodically, but the point is for dogs and other predators to see the "eyes" and assume another dog or predator is already there and "watching them". Reviews have been positive from what I read. Maybe you should consider looking into something like that to help deter the 'yotes and any other predators. Or even motion sensor lights. I would also make a point of securing any areas your birds are kept/cooped in at night so that you don't wake up one morning to total devastation. Chicken wire is easily ripped apart by a hungry animal. Welded wire has been a saving grace for us.
Do you have an outside dog? I find my dog has been the best predator protection I could ask for. Especially during the night. During the day, my guineas always kept strict patrol and were always first to alert at any problems. Which was great bc even if I was inside the house, I could hear them and be able to come running.
And this may sound strange, but I would also recommend peeing in areas surrounding your property and even near where your ducks are kept. If privacy allows, or just bring it out in a container and apply. It's always been an old-timer's trick where I live and it has worked for many. Coyotes want food, but not to have to deal with you. If your human scent is everywhere, that acts as a deterrent and may cause them to move on and forget about your "delicious goodies".
