Fajr has suddenly decided he absolutely hates the twins. Perhaps this is the result of seeing other family members shower affection upon them. Perhaps he hears birds sounds from downstairs, sees the twins go down there for hours, and knows that he isn't allowed down there, and has put all this together and become angry. I honestly do not know. We know he can differentiate between them because he snubbed one from a very early age, but lately he has become extremely aggressive, flying after them to chase them out of rooms, biting them in sensitive areas with the intent of hurting them as much as possible (Lips, ears). They used to feed him at the same time as their birds, but I've taken over this as he will angrily come for them and I don't want either the twins or Fajr injured. This has been going on for about a week, maybe a day or two less. He is about a year old now.
Because I know you will ask:
Morning is gloop-mixture of fruits, greens, veggies, with lentils and brown rice.
Night is a bit of seed.
Light schedule- sunrise to sunset.
