Nice conversion with lots of pictures. Needs more details. The dryer vent was a nice touch for ventilation; it looks like it would help prevent drafts during the winter.
Nice work in creating the run and making the shed into a coop. Not sure if I like the roost window being outside of the run; just worried about a predator coming at night right where they are sleeping. Agree about maybe needing more ventilation and my hens would fly or jump right over that fence, but your look happy, so Good job!
