one of my birds, oran, gets pretty territorial towards the other birds over the perches in the cage. especially at night time, when they’re all trying to get onto the highest perch to sleep and she keeps them off. she also started sitting on a new perch i added, and is starting to kick the others off of that one too. i‘m guessing adding more perches/swings for everyone to sit on would be a good idea, but is there any way to have her share more?
