There are Zadul to be found at different locations all the way up to Alpha. I'm fine with that. However, I prefer to hunt max maturity, that includes the Old Alpha, Provider and Stalker, which currently don't seem to be in the game. And this might not be the best place to ask, but do we have to wait for land area owners to collect some DNA and set it to max maturity? I have finished Ostelok on max maturity, and only got 6k Halix left to kill, and looking at the next mob to finish the mission for. Currently, without the max maturity, Zadul just isn't attractive for me to hunt. Probably I'll go for Oro or Nusul, but like to finish Zadul rather sooner than later on max maturity.
