I need to dust my chickens for lice and was wondering what might be the easiest way to go about doing this. Does anyone have any suggestions? This will be my first time and I don't want to over powder them or miss any spots that are important in killing the little buggers. I want to do this right the first time. I think I read somewhere to put the powder in a sock for easy dusting? Just pat it around the bird and the dust will come out lightly?
