I am treating my girls for SLM also, it is defiantly trial and error. My thought is if you find something that is effective, use it. Some individuals have strong opinions and can't keep an open mind. I used to be on BYC everyday but due to the "know it alls and opinionated individuals" I only occasionally visit this site. I've read all 62 pages of this thread unfortunately all of the good information could have been found in the first 5, the rest was one individual pushing their cure after saying some things work better than others for SLM. We all care about our fowl or we wouldn't be here searching for answers. Remedies such as kerosene and gasoline were used back in the day because there were no other alternatives, that is not the case now. I understand why some may try this route and its only because they read it worked, no need to criticize, we are all here to learn. Best of luck to everyone who is batteling SLM, hang in there and the only dumb question is the one that is not asked.
