This is my sons 1st year in 4-H and he will be showing a chicken (black orp cockeral). Anyways during the meeting tonight our county poultry leader said prior to fair to "shake and bake" our chickens w/ Sevin. I asked him to clarify and he said to put Sevin in a feed sack and place the whole chicken inside, close it, and shake. I told him I had read (here on byc many times) not to get Sevin into the lungs. He said that your suppose to get it inside of the chicken otherwise you can't kill the lice inside. So what are all of your thoughts on this?
