The vast majority of the young will die soon. That's simply the nature of most invertebrate reproduction: large numbers of young (in this case up to 1,000) with very high mortality. Protecting them would be tampering with natural processes and making them no longer wild tarantulas; don't do it! They are dispersing, and those that survive will make their own burrows. They've been in the burrow with their mother 3-6 days since hatching; she will emerge shortly.
