Hello I have two cockatiels, bought as a couple but six years later, not an egg in sight, so I presume they are two males, I know for a fact the grey is male, I have recently rehoused them, with a large nesting box but this is basically for warmth, they both love it and are constantly inside, they have always got on ok or mostly, one seemed to chase and chatter after the other and obviously the other one didn't care for it much. Recently they have started having quite vicious fights, no injuries but rather alarming to see, are there any options, I havnt really the room in the cage to get females?
many thanks
