Ogress, I hope your birds are doing better, I read on a later post that the disease is going through your flock - that stinks.
I am not familiar with Oxine but have read that others use it and love it. Another product I keep saying I need to check out! You also might also want to consider adding vitamins and electrolytes to their water a few days a week. Just trying to think of things I did... I am certainly not an expert. I know when my flock was sick I was looking for any and all recommendations - you can always weed out what doesn't sound reasonable to you. This might keep the non-symptomatic birds from getting sick. Yes, I think it was South Bend. LOL... 30 years ago was a long time ago! I would be surprised if anyone on here knows where Cathlamet is! We are looking at the Colville/Kettle Falls area in Stevens County for retirement. Another area full of small towns that many folks have never heard of.
I am working on coming around to full circle.
