I read that whole thread.I know, right? it sounds too good to be true. At least if it's not helpful for the chicken I can still use it to sanitize my milk containers!
It can be complicated between activating(toxic, but kills everything[-cide]) and not activating(safe, but only a 'reducer'[-stat] not a full killer).
There are many different uses and thus different mixing ratios....and like any other 'bug killer' it can be overused and create resistance.
Be careful.
