Are you saying you had 25 chicks in a 12" by 12" brooder? If so, that is way too small, and probably the cause of the problem. If 12' by 12', fine.
There is a product called BluKote, or something like that, that you spray on bloody spots to prevent chicks from pecking the spot. Anti peck I am sure is a similar product. People also use things like Vicks, tea tree oil, even Vaseline, along with some of the remedies you mentioned. But these are for small spots. You could try it but I don't think it will stop anything as full scale as the cannibalism you are describing.
How awful for you. I have never seen anything approaching this. But many of us have had to deal with more minor pecking issues, to pevent them from reaching this point.
Good luck.
