I know this is an old post but I’m looking to build a run with an arched top like yours for my chickens. I’m tired of ducking under netting and want a 6’ tall wire top structure. Is that bent metal conduit I see at the top? If so, how did you attach it to the t posts and what’s the width of the run? As I remember it, the conduit comes in 10 foot lengths.There are lots of ways to use Tposts and livestock panels...tho the clips may not work with the 1/4" rods on the LS panels.
But look for 'hoop coops':

I used Tposts and 14ga 2x4 fencing...but went extreme DIY for the rafters.
