I brought home 7 birds last night and at least 3 of them have moderate to severe cases of leg mites (the lady I got them from told me it couldn't possibly be mites cuz she had just treated for them with Sevin Dust...but it's pretty obvious that's what they are. Here is my question: I've been reading thru leg mite posts & have seen Vaseline, various oils & diatomaceous earth mentioned in place of using the Sevin Dust. I have no clue where to get DE around my small town and if I do find it, how expensive is it? As for the Vaseline & oils, my run is all sand. Is this going to cause my chicks problems with the sand sticking to their legs or does that matter? If I do "oil or slime" my chickens, what about the coop & run? Should I still use the Sevin there or is there something that may work better?
