the one thing I found to work with the case of whatever this is is the acidified copper sulfate. I tried the nystatin, both oral and ointment, nothing...well it did slow it down for 3-4 days but then it just came back. I finally ordered this stuff from Jeffers and gave 1/4 tsp. to a gallon of water for 5 days. It's gone. I treated everyone except the chicks under 3 weeks of age and other than one dirty bottomed girl, can't catch her to clean her, the brat, no one else has anything now.
Michael Apple mentioned something about mold...I'd like to throw out an observation I have made, repeatedly, with the feeds available from the farm stores. A lot of the bags of grain I have been getting have clumps in it. I've also noticed a slight stale/musty smell with some. I take these back. This is mold in the feed. Maybe not much, but I think enough to cause these troubles some of us are having. Something else, the feed we've been able to get lately has been extremely dusty. Is this because it's been sitting around a long time? Been mishandled? [ I find that hard to believe because the Blue Seal bags break if you breath on them!] Or are they using the bottom of the barrel to fill the bags? According to the dating on the bags, they're fresh, but contents tell another story. If it were one or even two...okay, it happens. 5-6 bags out of 15? That seems a little high percentage wise. Maybe I'm off the wall with this, it's entirely possible, but it was after the grain started getting dusty, that this gleet showed up here.
