I think this is a good discussion. Minus the technicalities of the definition of "free-range."
I've noticed birds of prey tend to be more active around the middle of the day, so I try to be more cautious about where my birds are then. Often times they are sleeping in a sheltered spot, under a tree or underneath our deck.
I believe the pee method works best when it is the first piss of the morning, because it tends to be more concentrated. If you've already had problems with predators, I think it would be less effective of a deterent than for those who haven't yet had a problem.
