Yeah I saw your location. You probably get more rain than me! I'm in Herts. I love North Wales. But only in the summer
I'm always amazed at the range of predators in the US, and count myself lucky we really only have a few here, and none that could kill a full grown human, let alone a chicken, lol.
I live outside of Chicago, to the west in a suburban area... if I go about 5 miles east, its Urban. If I go about 10 miles west, its Rural. So I am in that little belt that looks like every suburban neighborhood you've ever seen on the Tele.
That said, in my area, I have personally seen the following predators strutting about looking for a quick meal: Raccoons (legions of them), Possums, Skunks, Hawks, Falcons, an Eagle, a very impressive Gray Crane, Red Foxes, Coyotes (just a pair... I call them the beach bums because they're blonde coated and look 'chill', to quote my teenage daughter), one very obnoxious badger, at least a dozen feral cats... but their numbers are slipping thanks to the other predators, and a rather lazy Woodchuck who appeared (back in 2015), and was an insult to his name as he appeared to know absolutely nothing about wood.
The Hawks and Falcons are the worst when it comes to going after my beloved chickens. They try on the daily, but all their attempts have failed so far, thanks to some chicken wire, and a pair of exceptionally loud and aggressive Crows that chase them all over when spotted.
I can sit on my back patio and watch nature in full action over here, and sometimes it can be very entertaining... but I still worry about my ladies, because chicken wire mesh might keep the hawks and falcons away, but a hungry Coyote or Raccoon is going to make relatively short work of it, predator apron or not. Hence, I lock them up nightly in a coop made of resin. I'm sure a predator could get into it, but they would really have to work at it, and it would be easy to spot if they did... plus... I have a motion sensor light on that coop now, so if any wily little critters come calling, they get the spotlight treatment.
