Straw bale, anyone?

Have any of you built a straw bale coop? I built a temporary brooder coop with bales, and I designed (and will hopefully be building next week) a full sized coop but I'm wondering if anyone who has built one has any "I wish I'd thought of that" or "I wish I hadn't done that" advice about either the building process or chickens in straw bale structures....
 
I wanted to do this for my goats and chickens, but husband does not.

I'm loving the brooder coop -- it only took a couple of hours to put together on an existing concrete slab (the front porch!) and the chicks LOVE it. It is really holding the heat from the heat lamps well, and protects them from the wind, reduces ambient noise so they aren't startled constantly, and they love picking the rambling bugs off the bales. I also realized that with the full size version, the noise will be seriously muffled, which doesn't much matter where I live (except to the degree that the lower their volume, the less they advertise themselves to our predators), but seems like it could be real benefit for those who have or want to have chickens in town but worry about noise...
 
I built a straw bale coop earlier this year and its working great. The first few weeks the chooks pecked and scratched at the straw quite a bit and I was afraid it wasn't a good idea but once they got used to being surrounded by the straw, they left it alone. In "interweaving" the bales for solidity, I ended up with a couple of half bales that project into the coop. At first I was concerned about the space these take up in the coop until DH suggested we could turn those into nest boxes. The chooks didn't need to be asked twice. They dug a nest into one of those half bales and started laying in it even while the coop was still under construction!
 
My friend made one every winter for her 4 ducks. She stacked the bales in a U-shape, almost a complete circle - but with one bale missing for a door, then put a sheet of plywood on that, then covered with more bales of hay. It was a total of 2 bales high. They survived -20 degrees with that style house, until the neighbors new dog discovered them.

Are you planning to make the structure permanent with plaster on the bales or temporary? I did a temporary one several years ago, then used the same bales for the garden, and the main thing I would do different would be to raise the bottom course off of the ground higher than the 2x4's I used. When I tore it down, I had mice in the bales, and gophers had pushed dirt up. But as I said, it was temporary with the end product being a happy garden.
 
The plan is for it to be a permanent structure, with a full rubble foundation. I know moisture from the ground is a major concern, so I'm hoping that the rubble foundation, with a layer of plastic and roofing felt between the foundation and first course will be adequate. I haven't decided yet about plastering -- I can see the benefits of it in terms of moisture protection and longevity, but I know there are some folks who have left their straw bale homes unplastered and didn't have major problems, so I'll see how much money, energy and time I have when the time comes. At a minimum, the lower course of walls will be wrapped in poultry wire to protect it from being picked apart. And if I really get motivated, I have a plan for a (at least a partial) green roof, too!
