Well, the girls haven't seemed to suffer so I'm guessing it's okay, aart. I didn't put any Neem oil directly on them, and where I have Permethryn down I I hadn't put Neem Oil there. So we'll see. All I know for sure is that at last night's check, they were actually resting very quietly on the roosts instead of stamping their feet, scratching and shaking their heads like crazy. I did see a few mites on the roosts - and I smooshed 'em with my little fingers! - but not nearly the amount we'd seen before. But a few mites make lots of mites pretty quickly. I'm just glad the chickens seemed more comfortable. We haven't won yet, but we're progressing, and we'll keep at it.
