All mites are not created equal - do you know what type?
My local "Chicken Whisperer" was complaining she found blood mites in the bedding of some of her banties just the other day and "removed them", but I didn't ask what she meant by "removed". I'm not aware of what they look like or how they differ from the more common mites I've dealt with in the past. I can get more info from her if you think you might have them.
For the common mites, I agree with the earlier comment that the usual mites seem to hide in cracks and come out at night. For that reason, I like to be able to clean my coop easily and thoroughly when needed. The area we now use only as a brooder, I painted the walls white and sealed every crack with silicon sealer. The mites tend to leave a sticky residue which turns black from dust dirt, so having light coloured walls makes it easier to find the nests. Those mites can go into suspended animation, so just moving the chickens to temporary new digs won't solve the problem. By clean thoroughly, I'm talking mostly hot water and something like dish detergent, and a scrub brush and what I call a "green scrubby".
Similarly, I make all my nest boxes removable so I can *really* thoroughly clean them when needed, then I dust them thoroughly with diatomaceaous earth. I don't paint them white, as the birds like them dark, but I do paint them thoroughly so the paint seals the cracks as best possible. I generally use left-over paints for this from the Bottle Depot (which upset Hubby as one lot was purple, which he seemed to take offense to, so the next lot were "dark puke green", which got him thinking that dark purple wasn't so bad!)
I also oil the perches. This is the one thing I'm willing to use canola oil for. Two 10 ft perches uses ~225 milliliters to which I've added 2-3 drops of teatree oil. Chicken lungs are fragile, so I've heard some people say not to use teatree oil, but when I read between the lines, I think quantity is the issue. A few drops on that much perch shouldn't be a lung issue - on the other hand, I can't prove that it discourages the mites any more than just straight veggie oil. It just seems that I've had less of a mite issue since I started doing it. Coincidence doesn't prove causation.
If your birds have lice instead of mites - they live on the birds and move away from light so you can actually spot them - my friend recommended watered down hand soap sprayed and rubbed into the chickens on a sunny day. Don't rinse. Pluck feathers around their vent. Detergent is too strong. The chickens *don't* like this and need to be able to sit in warm sunlight to dry quickly, but I've been amazed at how quickly it works. If there are signs of egg sacks at the base of feathers, repeat every 10 days until you see no signs on inspection. Normally the eggs will be on the chicken's breast area near the vent, but one year in the hot weather the nests were out on the wing tips and I missed them the first time around - sneaky! If you do decide you have lice affecting a lot of birds, I recommend you get one of the pump sprayers that you pump pressure into and then just touch a trigger to get it to spray. The squeeze bottles like window cleaner comes in is really hard if you have wimpy hands like I do and you need to treat more than 6-8 birds. This process also goes much easier with two people. This is not something to do prophylactically - if you can't see lice, please don't put your chickens through this, but if you do see lice, it is the least poisonous treatment I know of.
For their dust bath, I have tried adding some ash from the wood stove, but if the problem is the mites that jump on the birds at night, I can't see that it would help and I worry that ash isn't that good for lungs either.
I realize these suggestions don't qualify as "organic", but you may be able to find organic equivalents.
