Pertinax reply;
I am tending to come around to that line of thinking too. I think they think(if you get my drift) that despite his lack of credentials,it is worth a try. The problem though will be more if it fails, what happens to him then? Does he stay, or be replaced yet again, and where would he go then? Maybe that will be sorted out later but in the meantime, for him at least, its certainly better than where he is now and he is getting his chance to show what he can(or not) do.
I was at Howletts last week and looking at Djanghou's very successful group(all of them born at the parks) and several infants. He was handraised too, and spent time in a male group also- though admitedly he was introduced to females at the earlier age of age 9 - but handraising does not seem to have affected his breeding ability at all.
If it fails with Kumbuka I'll have to remember not to say 'I knew this would happen' though.

As you said, if he turns out to be no good people will be saying' what did they expect?'.
