Ok. So i saw this http://hattiesburg.craigslist.org/grd/2759695525.html on craigslist. I'm not buying it.. But i'm hoping i might could get my dad to build me on like that. Could i use something about the same as that as breeding pens. I'd like to be able to hold 5-10 chickens in it. What size do i need to make it, if i'm not including a run.
