My western just went 8 months without eating. I can say, however, that I just got her to eat successfully by dipping the F/T pinkie in tuna fish water, from the can. Remember to use water, and not oil. But apparantly hoggies can't resist the smell of fish. That is for a western, I'm not sure about tri-colors. You could try it, though.
Are you keeping them seperate? If not, I'd suggest seperating them, because that might reduce stress.
