You should never tether period! Even if it's one leg they can still try flying because they "forgot " they were tethered and the leg can pop out. That is not the peas fault. They are too strong and it wont be an accident because you were warned. I was in. 4H for years and now I'm a 4H poultry leader....never have we asked to do this to birds being shown. I am sorry you don't understand as much as you think you do. Good luck in the future.
