Thanks for responding!
I assumed it was food aggression as well. I have always fed them before they get up. The only instance I’ve seen Aurora display dominance is when I put Saphira back in the cage with her after giving the antibiotic. Maybe Aurora got jealous of this because she could smell it?
They have been doing pretty well since separating them. The only thing I’ve noticed is some over grooming around Saphira’s ears. I’m spending extra time with them, so hopefully that will resolve itself in time.
