And increasing the amount of available prey will inevitably attract more and more predators to feed on it. It's nature, all part of a cycle. I'm not against trapping, I just don't think it makes that much of a difference. In my experience it hasn't. I trap one mink, literally the next day there were two more in my duck pen. I saw them, trying to drag off a dead duck. After that experience, I put all my effort into reinforcing my coops so that absolutely nothing could penetrate them at night, and stopped trying to trap everything. A year later and no more predator deaths, and all my animals free range during the day.
Not sure where you live but I live in the suburbs of a major city, we had a coyote training kill (adult mother with two sub-adult cubs) here- lost nearly half my flock in murky (overcast) daylight (about 2:00pm.
That was 13 chickens (all three roosters) and 9 ducks (ducks and the three drakes, one coward drake survived).
The adult was taller at the shoulder than my Pitbull who gave good chase, only slightly shorter (2-3? inches) then the female greyhound who didn't go under the hose to give chase.
