My BO was almost dead the other day, only thing I can find wrong with her is tiny brownish red bugs on her vent- in the day- which I am certain must be Northern Fowl Mites. She's only 3 months old, I've separated her from the other 5, but I'm sure it's only a matter of time before they have them too. I have hunted all over town for a cure, the feed store is back ordered on dust- he said "de-louser"- not sure if this is even what I need???! TSC was useless. Sick hen is improving with babying, though she still has a lot of mites. I live in Ontario Canada, and after searching all over the place for SEVIN I was informed by a nursery that it is banned in my province for several years now! I would really prefer not to medicate orally, I don't have very much $ at all to put into this, and I've got 3 littles underfoot here. Is there any other dust like SEVIN I can find in local stores here? Oh and FWIW, my van is in the shop till Monday so I can't go to another city to find another cure. Please help!?
