Thanks so much. I know that gas thing really sounded barbaric! Believe me, I searched for hours and found a lot of info saying it basically kills everything including the nits, so the life cycle issues are null, as well you are getting every part of the foot and leg covered, infiltrating all the affected area. I hate it, and I thought the hens would freak out at the first touch of gas, but they had no reaction which relieved me. I will think about your advice, I mean it, I will. I just have no way to cover or "suffocate" these things on these feet as they are a MESS. So unless I can find something else that can get into every crack and crevice, like a full dip type liquid, I don't have any choice. I read about sprays, but it would have to really get a chance to penetrate I think. Any other advice or ideas are welcome!! The gas was the only thing I found any info on as a sure fire dip type cure, and sometimes old ideas are horrible, sometimes they are good, who knows? The DE dusting was just to give them and nice clean feel and I know if they could, they would be dusting them selves.... It is what I have here now, but the permethrin 10, is that like sevendust? I hadn't heard of it, thanks!!
