Ok. I have nearly completed a house for my, soon to be delivered, ducks. I used 1"x1" welded wire on the porch portion of the house. After reading some of the posts in this section I am doubting whether or not it will hold up. We do have raccoons, foxes, coyotes, and cats around our area. Should I add another layer of the welded wire slightly offset from the first? I do intend to add more screws and washers to secure the welded wire better. I will post a picture so that you can see what I am talking about.
