So I've had my Kakariki for just over five months now and for the first 2 months everything was fine. Maybe about 3 months ish he has becoming quite aggressive when I try to remove his food out of his cage, I only do this when I need to change food or give him a top up. He will see my hand coming to his feeder and bite my hand. side note I can tell it is more of a warning bite than a full force bite. I believe his has developed cage aggression because he use to come out of his cage quite frequently but now he just spends all day in his cage and when i try to remove him he just flies back to his cage. Any advice would be great help and very much appreciated.
