Can i build a run with hardware cloth on the bottom (as it comes 50 feet long, 4 tall) and then chicken wire over the "cieling" plus the remaining foot-ish between the top of hardware cloth and the "cieling"? I plan on adding some shade features to the cieling. Also what size run for 6 leghorns if they leave their run a few hours a day and have a 1/2 acre to roam when "free" ?
