I am wanting to stop my turkey's from jumping on the roof of my buildings and on my cars. They are free range Royal Palms. I've heard about clipping their wings to prevent them from flying, but should I cut both or just one of the wings? I am afraid that if I just do one wing they will still get on the cars. They aren't in a pen, so climbing up a fence in not an issue. Also, how often do I need to trim the wings? Should I not do it on certain age birds, like a two week old turkeys? Thanks!
