I'm not sure what country you are in, but here in the US a baby or even adult goes for $15k to $20k or more. With that in mind, there is no way a breeder is going to ship an egg. Why? Because even for chicken eggs, the hatch rate with a good shipper is only 50%. It is pretty easy to replace a chicken egg, but much harder and more expensive to replace a black palm cockatoo egg. It's just not worth the gamble when they could hatch it themselves and make guaranteed money.
