You have been given some good advice. I have electric wires around my coops and pens and have a lot of predators. It will lurk looking for an opportunity and you may or may not see it and when you least expect it, it will go over or under a fence to get at the birds. Lessons learned the hard way. This is the time of year they are out looking for mates and then will have their kits to feed. I'm sure it is aware of your birds. Good luck...
