Keep in mind that whatever you treat your chickens with, the inside of their house must be treated as well...including nests and roosts. They must be re-treated in 10 days to kill lice/mites that have hatched since the first treatment. This is true for chickens as well. Sometimes a third or fourth treatment is necessary if the infestation is out of control. Without second treatment and treating the inside of the house...you are wasting time and money while the chickens can possibly become anemic, then die in given time.
