We are almost through hatching in our yellow-eyed penguin colonies and have many small chicks. Almost all of them need to be treated for Diphtheria, so it's head down and bum up for everyone trying to save the chicks. If they die, they won't fledge and there won't be any chance of young ones starting to breed to replace the breeders that die - and then the population will never recover. Needless to say that a ferret passing by Stitches' nest is a problem we don't need on top of this. We had a camera on her nest because a pair of penguins that had failed were spotted in the vicinity and we wanted to see if they are being a problem. Now traps are out and our wonderful rabbit hunter has been notified. Lets hope there are enough young rabbits, mice and rats about for the ferret not to take an interest in the young penguin chicks!
