I recently got a budgie, and I have had a green cheek conure for a bit longer. I have tried introducing them outside of their cages (after a few months of being in the same room, just seperated in their cages), but it went very wrong, which is almost always the case for introducing new pets. But the budgie's behavior was strange. I thought she was being aggressive, but now I'm not so sure. She kept running towards my green cheek without her beak open, just running over and looking at her super close. My green cheek kept running away and getting really stressed, and eventually chased her away with an open beak, and I was finally able to get my budgie back in her cage (she just kept hopping off the perch and going towards my green cheek). I'm not really sure what was going on? Was she just curious? Or threatening my other bird?
