They usually get along very well. Yesterday, they had a fight, grabbing onto eachother and trying to bite their faces. We separated them, then put them back together, and everything was fine until now. They had another fight, and one is bleeding from the head and leaving little bloody footprints all around.
Both are missing large tufts off feathers. This has really shaken me up for some reason. They are separated again, and I'm buying a second cage tomarrow.
