Hmmm yeah hormones could be at play for sure, especially in a new bond. I’ve heard it can take up to 6 months for female hormones to drain!
I don’t think a week is long enough unfortunately, since someone got bitten seriously and they are still trying to fight.
It would be best if they are unable to see each other, so if you could add something to the barrier it will help them calm down and forget the fight. In separate rooms would be ideal, but if that’s not possible, add cardboard or something to block their view of each other.
1 – 3 months is usually recommended, but if they are in constant contact, I would aim for 3 months minimum. Then you can start pre-bonding and see how they react. If they keep trying to fight through the bars, then they probably still remember the fight.
So sorry again, it must be so sad and stressful for you all.
