Did you dust your hen with DE or sevin dust. I highly recommend the sevin dust. Since your looking at a possible mite/lice infestation in your flock, go ahead and use the ivomec injectable first, rather than the wazine first. Dosage for the ivomec is is 4cc/ml per gallon of water for 2 days. It must be their sole source of drinking during the 2 days. Repeat same dosage and times in 14 days for your mite/lice problem.
