I wouldn't use DE and I would use the FF and the ACV....sounds like she may have an overgrowth of cocci in her bowels? This shouldn't be any threat to YOUR flock because you have the remedy for all that in their bowels already from feeding the probios necessary to keep an overgrowth of cocci in check. Whatever is going on in there is probably going to be corrected with the use of the FF and ACV. Should be interesting to see all that go away the more she is inoculated with good probiotics.
