You know, I just have to add this....after reading predator posts on this site over the past couple of years, I have really concluded that people lose more birds to predators who are cooped up in a pen, compared to those who free range. When they are in a pen they can't get away.. and all the predator has to do is corner them. When they free range they usually (but not always) stay with each other, and there is safety in numbers. At least if you do lose them when they are free ranging usually it is just one at a time, and the others know to be on their guard. Just my personal opinion.
