Well, I don't know enough about these collars. But, I am an avid animal lover, and am also of the mindset that it's better to put one down (humanely of course) than have them live their lives in a cage, on a chain, in a stall - maybe with a rooster collar on. It's all about quality of life for me. We think we are doing all of those sweet kitties a favor, for example, by keeping them in shelter cages, but I think they suffer and it's better to just let them go. Same might go for the roosters.
