My turkey is approximately 8 months old and is EXTREMELY socialized and loves people. She's always been aggressive towards other animals and scared of other birds but she absolutely loves to cuddle with people. However, starting around 2 months ago she became aggressive towards my cousin. They've never had problems before and he did nothing to to ask for her anger. She was sitting on the back of my chair with me as she normally does and he came over to say hello to her and she began to turn red, raise her head, and threaten him. Ever since then, she gets mad just from seeing his face and turns into a complete brat and wants to bite everyone. Just recently she began doing the same to my aunt. She's never been aggressive towards a person besides one incident where I took her to the fair. Me and the her were alone in the cage together then a friend rushed in suddenly to join us. The turkey became aggressive towards her, but in this case it was understandable. My friend was a complete stranger and she intruded into the already cramped space and it makes sense that my bird would've become protective and territorial after being startled this way. Why is she suddenly turning aggressive towards certain people without even being provoked?
