Wow, how recently was that? Are you talking about the Hillside collection mentioned on this thread? Was this open to the public at some point, and now works as Blackbrook's off-exhibit facility? (sorry if I'm making you repeat yourself on this forum).
I guess, once part of EAZA, the history of your institution having expertise with breeding Kings, macaronis, and rockhoppers, would put you in good stead, with a good enough penguin facility, to recieve this species over other zoos should they become available in the future?
I can't think of many collections with experience in breeding all three of those penguin species. Drusillas park maintain the ESB for Rockhoppers but have maybe only ever had one chick, and are down to one pair from the original three pairs. The only UK collection appearing to be breeding them lately is Whipsnade, but the group is not increasing in size, the chicks seem to be sent to London rather than build numbers up at Whipsnade.
