Wood Studs With Mositure

I found this post interesting with regards to how homes are built. The idea of a tree truck turning into a wood stud for framing. The processing and transportation from the Mill to a pallet to the job site or factory. It makes one wonder if the contractor is measuring their moisture content. It makes one wonder if the climate (where the home is built) and exposure to the elements impacts the wood stud’s moisture on the pallet during the framing. The idea of the stud in the wall with moisture does it evaporate and condensate within the walls to create mold?

What would be the moisture content of the studs in Rain? 100%? Probably!
