Unlike a bird that has been hung to mature a while ,there isn't much smell to gutting a fresh killed chicken. Cut from vent to bottom of breast bone allowing yourself room to work.There's no need for Vick under your nose ;D if your smearing that about you will end up with a menthol tasting chuck. Must have a look at this on Utube..
If you do the job outside I doubt there would be any smell at all....
