Hello, I have a 6-7 month old beardie named Khali, we assume she is a girl since we tried to identify her sex by looking under her tail. She was a big scared at first when we got her and we understood, after having her for a while she was fine and would be on our shoulder and cuddle with us when we would lay down. Recently, in these past month, she has been aggressive, she puffs up her beard when she sees us or when we try talking to her. She has been bullying our other dragon Pablo who is a girl. She’s been bobbing her head at her and getting on top of her. Is she a boy? Why is she suddenly aggressive towards us? We’ve done nothing that would cause her stress, we haven’t changed anything. Pablo and Khali have known each other since they were small, Khali would not care for Pablo when they were next too each other, and now Khali bullies Pablo and is aggressive towards my partner and I.
