Not only have I raised many sets of chickens inside fridges, but I'm also the only person I know with any experience. You can claim that you have read many articles, anyone can claim anything. Giving a link to an article about using a fridge for chickens can only lead you back to me, because I'm the only one who has done it at this point. As the sole source of information on the subject, I can authoritatively state that chickens benefit greatly from an artificial cavity like a fridge. If you can link to any other article on using a fridge for chickens on the internet, I'd love to see it, it would be a first.
