What ever resources we have makes sense to use. Sometimes we just have to use our noodle. Before we got Missy I never had anyone of my flock chew the trees bark etc. my gander being raised with ducks I guess he just never did goosey things, but first year we had Missy I learned just how chewy geese are now things I want to preserve having fencing around them. She completely chewed the bark off a Forsythia bush first winter here. My 2 new ones are chewers too.I use old wooden packing pallets as "tree guards" until the trees are big enough that my sheep can't eat them to the ground. Has worked quite will to keep the horses off them too.
