OMG! When I started reading this I couldn‘t believe how much my learning experiences mirror yours. And, when I got to comment about your frustration with your previous owner’s use of spiral galvanized nails, I laughed out loud - the destruction that has to happen just to replace even the smallest bathroom vanity at our house. Carpenter friends curse the previous owner/builder out by name as well - but tell me to rest assured we‘ll be safer when the big earthquake hits.

I must go back and keep reading though, because I still haven’t given up on the frustrations of the walls under the slant roofs. I’m starting a new coop and run this week and my wheels have been turning for days on how I’m going to cover the coop and run - as it will be home to white silkies and a couple of frizzled feather foot chickens and it needs to be dry.
Anyway - there appears to be years of ’good stuff’ here, so thank you to you and others for takimg the time to share.
