Treated lumber or not?

[kiwiegg]

I've chosen the 8x8 walk-in from "Building Chicken Coops for Dummies" and will make some minor changes. I want to build the coop at an easy pace for time and budget reasons.This design is going to take a lot of 2x4's.Obviously untreated is less expensive than treated but I'm wondering how many wet days the untreated framing would be OK if left exposed? The framing is going to buttoned up from the elements of course once the roof and siding is on. Thanks for any input.

In FL treated lumber is a must- not sure about your area.

You might want to check on treated lumber as opposed to untreated in the price department. Around here (western kentucky) treated 2x4's are cheaper than untreated. At Lowe's treated 2x4's are $1.97 and untreated are $2.38. It may be a different story in your neck of the woods. All of it will warp when rained on and then left to dry in the sun. I think treated will warp worse, at least in my experience it has. I just build everything out of treated because it's cheaper.
