Framing questions - weather issues

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!

I would worry more about warping and blowing over. Until you have a 'skin' on the building (or good thorough diagonal bracing) there is not a whole big lot preventing things from going somewhat or entirely cattywhompus.

As far as just the effect of weathering/rotting the wood, it depends on the situation. IME plain (non p/t) lumber outdoors does not do too terribly over the span of like one season or one year if it is up off the ground and supported in a way that after it gets wet it can all dry out again reasonably quickly. Like a fenceboard, or exposed pieces of structure of a building. However if a winter's worth of snow lays against the bottom part of the wall, or if it is among dead grass or a drift of leaves piles up against it, that portion will *not* dry out so well in between wettings, and may very well have enough rot set in that it softens undesirably and you lose a significant amount of longevity. So it kind of depends what your situation is like.

I would guess in Minnesota, though, that snow, if nothing else, would be an issue and thus I would probably be disinclined to leave a bare-bones-frame-only shed up over the winter. At the very least, use screws or double-headed nails to slap some THOROUGH diagonal bracing on all four walls and the roof, to increase your chances of it still being upright and squareish come springtime.

(e.t.a. - no, don't use treated wood for your framing (except the bottom sill). It's kind of a waste of money and chemicals, it's heavier, it's crappier wood (more inclined to twist and split), and has much more stringent requirements for what screws/nails/hinges/etc you use. Plain ol wood is FINE, since it will be covered by siding and roof.)

JMHO,

Pat

Minnesota is a real winter challenge! I agree about getting the work done, including the roof and sheathing and using treated lumber. Be sure you have a door.

We're building a second coop in our barn at this time, there may be ideas in this file that will assist you.

Kiwi, How large will your coop be? If not to large it could be covered with a tarp. If you can't get it closed in, I'd wait till spring. Framing it all with treated lumber,
would be a waste.

Thanks Luckytaz. It's going to be a 8x8 walk in with a 9' peak. I think you are right about waiting re wasting money on treated lumber-you know the snow will be here real soon. I do have plenty of room in a detached garage so I might just start making floor and wall frames and keep them in garage. Once I get a bee in my bonnet....

Mine's 3/4 done, an A Frame and I have stained and waterproofed with Thompsen's. Looks great and in case I don't have it completed before the snow flies, I'll not worry. I'm not getting my birds till Spring.
