We can hear the coyotes almost every night. You can get them singing by howling to them. It can be pretty eerie. Our property is on the side of a mountain, rural, with lots of tree-filled canyons between the fields and small farms. It's about perfect coyote habitat. I gather some of the neighbors also sometimes see big cats (bobcat? mountain lion? whatever is indigenous around here ...). And the hawks ... oh my the hawks. Owls. Bats. Neighbors dogs. Deer that eats the farm stuff but not chickens (so far). I'm just glad we don't have bear or rattlesnakes. I feel pretty okay about the chickens -- their coop where they sleep is about as secure as one could expect and they have a fenced pasture that is secure-ish to play in during the day. I'm not that worried about the turkeys because they also have a pen at night and are on "limited time" anyway. But the ducks are escape artists ... they do let us put them to bed and do sleep in their pool which is in their pen, but they get out of their pen very early in the morning and that's when I used to see the coyotes out roaming around looking hungry (and anyway if the ducks can get out of their pen, then pretty much anything could get in). I think the ducks are even more defenseless than the chickens because they can't run very fast, can't fly very well, and can't even hop up into a tree to escape an attack. We need to button up the duck habitat. I haven't seen any coyotes close to the house/coops since we got a dog. He isn't a guard dog (he's actually a bird dog!), but he does mark his territory in some conspicuous ways and so far that has helped keep the wildlife away.
