Since you tried different proteins and he is still having diaherra, look at the carb source (rice, peas, potatoes etc) and see if they are the same in both the TotW recipes. I believe TotW mainly uses peas, so consider that he is intolerant to peas and try a food that does not contain them. I know you want to do grain free, but because you know he can handle chicken and rice, try a food that is chicken and rice based. Or at least find a grain free food that does not use peas as the carb source.
