We had to have covering over the top of our chicken yard. The hawks in the daytime and the cougar at night. the night time wasn't really a problem though, we just closed the doors every evening.
We did run a stand of hot wire at the top of our 4 foot stock fence, to keep coyotes and dogs out. We never had a problem. But our neighbors sure did. Lost lots of sheep and other small stock to marauding dogs and coyotes.
