DH put the prch up on Monday, and it was so worth the trip!
We ut it up against the L shaped part of Henopolis, so we only needed to build 2 sides (one o fwhich was the double doors) and a roof. We used a flat panel for the roof.
Now, when I'm herding that last recalcitrant hen, I can keep the others shut inside while I do so. It's been used for its intended purpose every evening since!
