I've been lurking online for a while now trying to do all my research before I pitch the idea to my wife. We live in the suburbs so I'm thinking a chicken tractor will work the best for us. Do those of you with tractors worry about the sprinklers? I've seen some really nice plans and designs on here and most are made of wood, do you move them away from your sprinklers at night or just don't worry about it? Thanks!
