Whenever my chickens have had mites and they've gotten on me, I've been bitten. But, I've never brought them in the house with me.
If your chickens are the cause of this, then they must be SEVERELY infested. In which case, you need to start treating the source- the coop and birds. Clean out everything. Spray down everything with pesticide spray (I use Adams Flea and Tick spray), bleach or strong vinegar solution, rinse. Let dry and then dust every crack and crevice with Sevin or something similar. I put a generous helping on the coop floor and under the bedding in the nest boxes. And guess what!?!?! After 10 days, you get to do it all over again! Doesn't that sound like fun!?!?! You HAVE to retreat. If you don't, you wont break the cycle and they will start all over again.
As for treating the chickens, you can put some Sevin in a trash bag, put the chicken in the bag with its head out of the top, then shake the bag around to give them a generous dusting. If you have lots of birds to treat, something like Ivernmectin (sp?) pour on might be easier.
Also, make sure you don't have fleas in your house! LOTS of people have complained this year about fleas, and their pets monthly preventative not working. We had a huge problem last year when our Frontline stopped doing its job. Even if you don't have indoor pets, you could still have fleas! If a neighbor, someones you've visited or has visited you recently or someone you've bought something from has an infestation, they can easily share them with you!
GOOD LUCK!!!
