what happen to penny? does she have any other children?
It has been mentioned before that all hybrid giraffe will leave the zoo and essentially will either be transferred to a collection willing to maintain a non-breeding herd of hybrids or just one sex only grouping.
Only Thorn and Aoifie will remain at Chester and from reliable sources we have learned that some more pure-bred Rotschildt's females should come in 2009/2010-ish.
So, Chester is keen to breed giraffe, but not its hybrid giraffes.
