Going back to the chlorinated chicken - is the concern the chlorine or something else.
Concern over chlorinated chicken should have nothing to do with the technique of chlorinating the chicken, which, if the chicken is cooked properly, is a non-issue. The concern is the fact that it is used to try and make up for dire animal welfare used in raising said chicken, which is a very valid concern and which can be sidestepped by buying high welfare chicken.
If your concern is chlorinated chicken populating KFC and other fast food outlets, I think that you have your worries warped as these places do and will buy poor welfare chicken as a business model anyways to keep cost down.
