Hmm 22 days old now.. That’s about three weeks old. I've never bred Roborovski before but I’m pretty sure that at about four to five weeks they should be weaned and self sufficient, If you don’t want any more pups you should separate the pups into male and female enclosures, separate the father too if you don’t want more. And then just let the mother raise the next batch.
Your not anywhere in the US are you
?
