Hi all! I FINALLY made it to my 5 acres in the country!! The girls and I made the move ok and I'm snuggled into my tiny house and they are crammed into the existing coop which is WAY to small and nasty. There is a large pole barn with a dirt/sand floor which I am converting to a coop/barn. The structure is sound with 6x8 poles set in concrete between 9 and 12 ft. apart and 2x8 horizontal framing with diagonal bracing. The exterior is some seriously heavy duty barn metal on 3 sides. the roof trusses are substantial. I am enclosing the first section of barn to make a coop. Question: can i build 2x4 walls, 16 oc and attach them to the existing 6x8's?
