We just moved to a house on rural property in alpine , ca. We have a bob cat at the end of our driveway, coyotes, and raccoons, skunks, etc. We are living on an old chicken ranch with old chicken structures. We are enclosing one of the old chicken structures...the end of it..and need advice on weather chicken wire or field wire is the best fencing. We are enclosing the top with chicken wire....the sides have field wire that is old....is a bob cat or coyote capable of breaking field wire? I understand the barb wire part of these posts. Is chain link needed against these preditors? I am new to this forum and look forward to learning from all of you. I am kate and an herbalist.
