I haven't read through the whole thread, but one thing I would advise is to separate their food bowls and teach each one which bowl is for who. Put the bowls at different ends of the kitchen or whereever you feed them and stay with them when they eat. When they are done, pick up the bowls and do the same at the next feeding.
I have four who are all trained to use their own bowls, and never have a problem with food aggression. |
