Difficult in her case means difficult with humans, not with other elephants. There is a very easy solution for her problems with the keepers - protected contact. Too bad that Whipsnade sticks to direct contact with all the elephants.
Much more understanding in the sense, that in Twycross she grew up with her family, so it would seem a little strange if she was aggressive to her fellow elephants. Then again it has happened before ( only cases I know of are in wild herds)
A captive born elephant named Komali born in Zurich was put down due to aggressiveness, however I don't know in how she was aggressive and who to.
Kaz, I just caught the GM.tv Anglia news this morning and the baby is now out on walks with her mother round the zoo. She is a mischievous little one and sure to be a great attraction.
