Sudden aggression in my male Conure.
I got these two Conures for three years now. They have always been very loving and kind to each other. The last two days, the male conure has become very aggressive towards the female conure. He tries to grab her by the neck and bites her feet as she tries to run away from him. Why the sudden change? Is there anything we can do to stop the aggression? Would we have to separate them now?
