I fenced my garden with the cheap black/green plastic mesh (NOT the flimsy 7ft
deer fence, you will trap/kill animals like snakes and possibly even your
chickens, the stuff is useless). They can't see a top to the fence so they don't try to jump it. When I first put it up, I don't think they could even see the fence itself because they would walk straight into it. Once they realized they couldn't walk through that area, they stopped trying. There's even a section, about 15ft wide, that my dog ran through and I haven't fixed yet. They haven't noticed yet and it's been a couple months. The side facing the road does have a wooden fence and my peacocks have learned they can walk down that and hop into the garden so just make sure there isn't something they can jump onto for them to get in...
