Kathy, I have always known you were a "mad scientist". LOL I have never done fecal testing myself. I have always found it easier to get it tested, although I have never had any real serious worm problems here. Round worms are the only worms I have ever had to deal with. And even then, at this altitude, VERY intense UV, and some of the driest dirt on Earth, LOL, worms and their eggs don't survive long. I have never had infestations.
So I can't help you with this one. BUT....if you do figure any of this stuff out, PLEASE enlighten me! I am always on the road to learning new things and I too love to experiment with things. A closet scientist if you will. LOL And the more I know, the better steward I am to my flock. So keep me posted if you know something about this!
