NH: Here is my method of dusting...... I use a small litter box. I hold the chickens by the legs out behind them with their bodies laying in the litter pan. I sprinkle the dust on and rub it in under the wings around the vent...try not to get in the eyes. The reason I use the litter pan is that I can scoop up the dust from the pan fo rthe next birds and I do not wastes it.
