I also have this problem and have switched my girls over to Nature's Variety Prairie(Raw) and have seen some success but it really is to soon to tell (I have only been using this for about 2 weeks).
One thing I did stumble upon is what I was washing my tile floors with was causing alot of the problems. I was using Pine Sol (I know I am spelling this wrong but to lazy to go to the kitchen) and it was really causing a problem. I have now switched to Ivory soap and it really completely stopped in the itching in one of my girs.
Hope this helps.
