Regarding Jitu:
Yes it could well be that he is a dud. He was only with the two older (now deceased) females and the young Apenheul female when I was there. However I'm not sure that the rearing is necessarily the problem. As I understand Stuttgart has an excellent record of hand-raising apes of all species for European zoos and then socialising them back into groups. That is not say they always get it right! I just don't think one can rule out factors such as enclosure design, stress and management of an individual, that under different circumstances may see a different result. I don't know how important genetically Jitu is but certainly Ya Kwanza comes from a relatively unrepresented genetic line.
Overall I think it is important that if zoos take on any species that they need to take on board all the requirements to manage them properly - not just because it is a big name species that brings people in. To my mind Blackpool could turn there gorilla enclosure into a chimp enclosure (which are alot more tolerable towards humans) and I'm sure the public would find it a more interesting and dynamic display. They won't, but that is another arguement.
