Hello everyone, I have a quit annoying issue with our CONGO African grey. My wife and I have her (female) for more or less 4- months now, but the problem is, ONLY my wife is allowed to touch and cuddle her. When anyone else tries to touch her (at the cage or not), she will make a loud, sharp noise - a mixture of scared & aggressive. Inside- or on top of the cage she will make the noise and launch for me and if she can bite she will definitely do it! We had the bird since baby (hand-reared) and my wife handled the bird most of the time, and the one day the bird was still ok, but the next day, out of the blue moon, when I touched her inside her cage, she bit me, and from that day on she was aggressive towards me and anyone else who want to touch her. For 2 or 3 days she had a great aggression towards me by 'blowing up her feathers' and striked at me, but it passed by quickly, but the touching/cuddle part still remains. Even if she sits on my lab she is so nervous and uncomfortable and looking where my wife is and just want to get away from me as quick as possible. I am not happy with that kind of behavior and it's not a pleasure to have a bird like that, specially if the bird cost R2 000 ($300) and I want to get rid of her and get us a male because I want a "family type of grey", but she and my wife is so much in love with each other and my wife doesn't want to let her go. She also bites my wife by times (very hard) but it's more when the bird is either 'moody' or when she sits on my wife's hand and someone else wants to touch her. Then it's the same thing again - loud scream and the biting. Can anybody please give me some quality advice? Thanks Jacques
