Echidnas are difficult to breed in captivity at the best of times because of their mating habits (I've put up a post about this before). Being an albino makes this little echidna very vulnerable in the wild because he has no camouflage so I imagine he will remain in captivity at the Symbio Wildlife Park in Sydney (the young woman who brought the echidna to the vet had the name on her cap). Because he is a young echidna I guess they will try and see if he mates in general. He is healthy and he should have a chance to exercise his natural instincts.

I'm not an expert, but albinism is generally recessive, so if they breed an albino with a non-albino it's very unlikely any offspring will have albinism.

No, I did not understand it that way. In order to intentionally breed an albino animal both parents must be albino. They wanted to know what gender it was. I'll have a look again. How did you get that impression?
