We adapted an old 6m x 9m gazebo, I bought anti bird netting from Gardening naturally,it’s in its 2nd year & still doing well. We put 1 piece of net around the sides & a separate piece over the top so in theory we could take the top off in the winter in case of heavy snow. It protects my cherry tree,blackberry,gooseberry & red,white,black currants & some strawberries. Most bought fruit cages are netting rather than chicken wire, not sure how the cost compares.
