The local store told me that for medium bird it should be ok for quail.

I have been following this thread. Thank you to TwoCrows for all the very useful and insightful information. Seems to be so much online about chickens but quail not so much!
I'm concerned my quail may have worms/mites. One has bald patches and looses feathers and she is always dust bathing...
