The purpose of house wrap is to be vapor-permeable, while also being liquid-impermeable. This reduces the risk of moisture buildup on the sheathing.
Rockwool is vapor-permeable, but last I checked it isn't rated to be liquid-impermeable, which means building code inspections won't approve it.
Practically speaking, I saw someone soak a scrap of rockwool in water and it didn't absorb anything in about an hour and water just ran off it.
I think the best building-science case for house wrap is to protect the sheathing in case the rockwool somehow fails.
Beyond that, the building code requirement may be the most compelling reason for house wrap.

Rockwool has the advantage of not tearing easily like house wrap. Rockwool won't irritate skin like fiberglass, off-gas like foam, or settle over time like cellulose. It also gives you continuous insulation, which seems to be way better than the equivalent cavity insulation.

I've seen chickens raised without a coop near upstate NY. They would nest in the lower branches of a pine tree at night. The property was sheltered by trees and enough people were around to keep predators away. I think the only care they needed was a temporary coop and extra food in the winter.

This was my experience also. The pots just didn't break down quickly enough.
The next year I used the rest of them, but I cut the bottom and sides before putting them in the soil.
I haven't used them since.

Naturally, several chickens have decided to shun the nesting boxes and lay on the far corner, where I have to fish them out with a fruit picker. It was a bought set of plans too, apparently not designed by someone who actually keeps chickens…



Lina, I had the exact same problem!
We have a net that we used to scoop them out of the far corner of the coop.
It was a coop I designed, so I have only myself to blame. At least it was only a 4' reach to the back of the coop.
My sister solved the problem when she made some small changes to the nesting boxes and all of a sudden the chickens love them.

Also, you might want to check out Carolina Coops on Youtube. He's got videos about why he builds his coops a certain way. I found it very helpful when designing my coop and run.

von Moltke the Elder said: "No plan survives first contact with the enemy."

If you're building your own coop, you'll need to customize it. It won't be a once and done coop, more like a slow-running project.
I've built two coops for my chickens. The first was very basic and I knew it had flaws. As it was breaking apart about 18 months in, I built a second coop and improved the run it was attached to. Since then, we've steadily fixed and improved it.

Side note about predators, we didn't think much of a squirrel who found a way into the run. Until a racoon got through the same gap.

Just found a related thread about the safety of wood cutting boards:

I didn't read the whole thread. But it sounds like a wash with soapy water followed by quick drying may be sufficient.

I had to do something like this, except it was my own cutting board that I let get stained and maybe a few spots of mold.
I cleaned it with salt and a little lemon juice. The salt was only damp so it stayed gritty and scoured everything that wasn't absorbed in the wood.
After that I sanded the surface until it was much lighter and clean looking, then coated it with mineral oil. I need to recoat it every few months to keep it looking oiled.
I picked mineral oil because I was sure it was food-grade and was easy to work with. I got it from a pharmacy.

I TOTALLY wouldn't do it but I have heard of someone who just keeps adding an additional "*" character to their usual go-to password every time.



My first employer had a rule that the password couldn't be any of the last 4 passwords, which ruled out adding the season to the end of my password. So I added the number of times I needed to change my password instead.

I think all of these will result in good passwords.
The US government used recommend a lot of complex password rules, but recently scrapped all of it in favor of a simpler recommendation (NIST SP800-63b):

Go long. At least 8 characters.
