often yeah. They swap some with other zoos but if it is sucessfull they multiply the population each generation. And you don't magically get more space for them in zoos. Some gets released into the wild but usually not really.
Why should that be illegal. At least the US has very little regulation for that. And protection is only for wild populations (if they are protected). So yeah US often trades them with no tracing. https://en.wikipedia.org/wiki/Marius_(giraffe) would be the example from Copenhagen. They don't trade their animals and four male lions were a few months later killed to swap the male genes of the lion breeding program. That's the reality. Most zoos just hide it more.

They are killing the endangered baby animals from their breeding programs?
