Thank You!

When I saw the wood the coop was made of, I thought "Oh boy...a rat is going to sneeze and blow a hole in the side of this thing." I was thinking of making a second shelter for them out of recycled pallet wood this summer. Do you know of any articles or threads where I can find some inspiration?
I’ve seen some pallet coops on here. If I find anything, I will pass it on.
I’ve had my coop since October. It’s not doing too bad. But, I made sure the coop/run was secure with extra hardware cloth and landscaping stones that we had just lying around.
We’ve had some good winds and it is still standing. I reinforced the latches with eye hooks and carabiners - or added it in addition to the latches.
I also gave it a good coat of Thompson’s water seal. I think that has really helped. With the snow, I can see where it blows in when the vent window is open and it’s coming from just the right direction. Grrr... I will remedy that - hoping this weekend. But, so far it’s doing what it was meant to do. We built a cattle panel run around it covered with welded wire after my in-laws dogs were able to get to the chickens with small run extension made of lattice that I didn’t reinforce at first.
We are planning on adding something to the top of the cattle panels so that they are safe from birds of prey. But, the chickens are only allowed out in that when I’m out there and confined to their coop/run set up when I’m not.
I added plastic around the part of the run that is under the coop - then added a tarp to the lattice extension so that they have areas that are dry and can still utilize when it’s snowing.
They seem secure enough, but you just never know with all of the stories I read here.
