I got a nanday conure about two months ago, I was told it is 2 years old, don't know whether or not its male or female. When I first got it my conure was very friendly with me. It would let me hold it and play with it and never showed aggression to me. Suddenly about two days ago my conure got very aggressive in its cage and seriously tries to eat me every time I go near the cage or open it to take it out. I'm not sure what caused this sudden aggression. I'm new to having a bird and have been reading everything I can so I don't make mistakes with it but I seriously don't know what caused this sudden aggression. Can anyone help me?
