Looking around I found this plan on the University of Tenessee extenion web site: http://bioengr.ag.utk.edu/Extension/ExtPubs/PlanList97.htm#Poultry%20Plans My question is has anybody built one of these? What was the cost? I am going to build one on modified down to 10' x 10' on a concrete slab that already exists. Any suggestion or help would be great. thanks Todd
