Airica

It’s just loose chicken wire on the top of the fence, about 24" of it all the way around, structured haphazardly. It is only tacked to the top of the fence and is very wobbly, stable enough only for small birds (chickadee size). I put it on to deter groundhogs from getting a good footing, but it seems to keep the squirrels out too. Not necessarily foolproof because squirrels are totally ninjas.

During the winter months, I keep my seed and suet feeders inside my fenced garden. That way, it keeps squirrels and other mammals out and adds a small amount of fertilizer (droppings, shelled seeds). It’s a pleasure to see them every morning!
