Hi all. I'm really amped up about starting my coop. I know that if I wait until spring (when we are getting chicks) it will be rushed and I won't enjoy the build as much. I live in Minnesota and although the weather is great right now, it is going to get nasty soon. So here is my question; I can pre-build wall frames in garage and have space to store them there, but I would rather get them onto base right away. If I'm using NON-TREATED lumber will a winters worth of moisture damage framing if I don't make it past framing stage? I intend on using treated for the base but was thinking of using interior grade 2x4s for the framing as my coop will have painted T1-11 siding and a proper roof and it's cheaper than treated. Or do I need to use treated for all framing? Thanks and I'm sure more questions to come!
