Hi there
@Pitikok, hope you're enjoying BYC!
Did you already check out the coops section?

I just finished building my coop.. Let me say first.. the cost of 2x4 literally tripled in the last 6 weeks since we started to over $7 EACH!
Since we weren't building a human structure that needed to withstand hurricane force winds.. we used a lot of 2x3.. where possible. like for the walls which were holding up light weight as we went with corrugated metal roofing.. due to cost but also because it will function better than traditional shingle style roof in THAT location with all the tree droppings, sap, etc. I expect sweating to happen just as it did in my pole barn where there was no insulation between the top of the roof and ceiling.. when the sun shined on cold mornings. One factor for roofing for me was actually sound.. I suspect metal amplifies everything and wood would SEEM to dampen it.
We also have super high humidity year round here.. and so used waterproofing, mildew resistant stain (or paint) on EVERY inch of wood BEFORE assembling. This added a huge amount of time, but will pay off in the end. Also, (I shop HD) by checking the "oops" paint.. I got a 5 gallon deck stain valued at $115, marked down to $30.. and it's hard to get a single gallon of quality paint for under $30! I will try to post a photo as soon as I find my phone.
OSB work fine as floor. (Noting I am an amateur about building, just a simple house wife with tons of ideas and projects yet limited resources such as time, energy, and funds). I painted both sides since the birds will be underneath.. and inside the coop also get a sheet vinyl layer between the OSB and shavings/droppings. I have used OSB as an exterior wood.. and it requires HEAVY amounts of paint to protect from the elements. It's a little uglier as well not being smooth. And the way Kung pow described bubbling etc on the pine is exactly what happens if not protected from moisture. I am in the Pacific Northwest and we average 50-80+ inches of rain depending on the year so moisture is a main factor for us.
T1-11.. exterior grade glue, primed on the outside already, perfect, easy to use..
Hardy plank mentioned another good higher end choice.. You DO get what you pay for quite often. My hubby's future consideration for coop exteriors.
I like the fence boards KP, and have considered them myself (up-cycled more than new due to cost factor but of course sweat equity ain't free). Looks nice though, and thanks for noting the difference in how the two material are holding up!
I also use half inch hardware cloth extensively, but find it cheaper on
Amazon than local. I haven't dealt with bears partly due to having dogs that roam my place, I think. It has effectively kept out raccoon, rats, opossum, etc.. when installed correctly.
Plywood vs OSB.. plywood is prettier and a little higher priced last time I check at my location. Also maybe stronger for a thinner product?? Come to think of it.. the coop we just built that is elevated but walk in has a laminated plywood floor, with the laminated part facing the ground under the vinyl that's inside. Our smaller coops that were not walk in were OSB, only supporting the birds.
What kinda birds are ya getting? Did I miss that.
Happy adventures!
