I'm not sure if this is the correct place to ask this but when you're sharing chicks locally what kind of boxes does everyone use? I started by just putting some pine shavings in a cardboard box and cutting holes in the side but I very quickly ran out of the appropriate sized boxes! I would like to purchase something inexpensive in bulk that can make my life a bit easier...those foldable lightweight boxes like the feed stores have would be perfect but I can't seem to find any other than the expensive heavy duty shipping boxes online. Does anyone know where to buy them? Thanks!
