Wow, we are at the start of a 4-day heat streak!. Not so fun working outside, but the other day my nest boxes in the chicken coop came crashing down, so I have started rebuilding that.
Actually, I have planned on doing some cosmetic repairs on the chicken coop for a while now, but it did not become a priority until the nest box rack fell apart. Yesterday, I started taking apart the damaged area and the work I took down, the more I found had to be replaced. When I built my chicken coop 4+ years ago, I used OSB for the sidewalls and then painted it. It still looks pretty good, but when you start working with it now, it just crumbles in your hand.
To be fair, I did not expect OSB to last as long as some other types of wall board, but, at the time, I never had laying chickens and could not imagine that 4+ years on I would still have a backyard flock. I opted to buy OSB and paint the wood rather than spending 3X-4X more on a higher quality sideboard. The painted OSB has held up better than I expected, but where it gets wet and does not dry right away, that is where the OSB is failing.
In addition to bad OSB needing to be replaced, I have had some 2X4's rotting out in the same section. I am literally having to replace and rebuild some structural lumber which I had not expected. I thought I was only dealing with some cosmetic issues.
The old rotted 2X4's are being replaced with pallet wood 2X4's and salvaged wood 2X4's but this time I decided to double up the 2X4's framing in that area. That area being the area where I open the sidewall panel from the outside to collect eggs. That is where water has run down the wall and rotted out both the OSB and the 2X4's. I'm only half done with the project, but it's already twice as strong as the original build.
I took some before pictures, but I'll have to take some progress pics in this case because when you see the finished product, most of the real work will no longer be seen. I'll post the pics when I finish the project.
Also, when I built the chicken coop, instead of buying good quality trim board, I cut some OSB down to 4 inch strips to make my trim boards. That saved me a lot of money at the time. I painted the OSB "trim boards" white and they looked OK. However, I am replacing that OSB trim with pallet wood planks. I suspect the pallet wood trim boards will last much longer and, of course, they are free so I don't even have to buy any new OSB.

OK, a little self-confessing needs to be done. I have built a number of outhouses and sheds over the years, but I always used higher quality wood in those builds. When I built my chicken coop, I wanted to save as much money as possible. The reality was that eggs at the big box stores cost less than $1.00 per dozen at the time, and I could not justify spending $1000's of dollars for a small backyard flock chicken coop, which, I expected to only have for a couple years. If I had to rebuild my coop today, I think I'd use pallet wood as much as possible - which is better than the OSB I purchased - and maybe double up on the 2X4's from the start. That would have saved me even more money and would have been a stronger build.

It's going to be a long day.... In this heat, I work a little bit and rest a lot. It's just terribly hot and humid and that is not a good combination for me. I hope to finish the project today, but if not, I'll be OK with it taking a bit longer. Later...
