Interesting idea, but the article needs more details like space between the cardboard walls for average chicks of this variety (quail, standard chicken chick, bantam, etc.) and how to build\design it. Even including a success story of a particular chick healing through this method with pictures of its progress would help this article. Also, details on how exactly it works and how it actually helps the chicks heal would be helpful.
Again, interesting idea. I'd love to know more on it.
