Well here chickens aren't covered in any protection act, which is a shame. There are a few folks I would report if there was..They used to do a lot of things back a few years ago more than what the law will let us do today. If we were to do something like that someone would turn us in. But if it worked why not do it. I am like you I will put them in a wire cage. I have also heard that you could spray their under side while in the cage with cold water to help break them Don't know if that works.
None of them ever died from it. Well except the time the lightning hit the clothes line..
My grandfather (the one who grew up with his father doing this) built me the most amazing nesting boxes last week.
Farming has been passed down in my family generation to generation. It skipped one with me growing up, but as soon as I owned my first house the chickens arrived.
