says, the keepers provided daily visits by Okanda to his mother while he was being hand-reared, but the rather instable group (Oumbie, Ozala and Asante) reacted increasingly nervously so there seemed to be no chance for a successful reintroduction. That's why the EEP recommended his transfer to Stuttgart nursery.
Sorry, Willard, I edited your post instead of quoting, by mistake...
Very interesting news, that's a much clearer explanation; better to be safe than sorry no doubt.
I think if/when Ozala has another baby she will be in a more settled environment if she again has the company/support of a 2nd female (probably two) and so more relaxed.(she reared her first baby Matadi perfectly, under these conditions) On her own just with Oumbi, she plucked herself heavily around the time of this baby's birth, indicating high stress levels, so the later problems weren't too unexpected I feel.
