I think one hamster was already pregnant on arrival and the other was going to be introduced but hasn’t been - is that right? It was just bad luck and it is very common for people to find a female Robo is pregnant - it happens a lot from pet shops as they don’t get the sexing right sometimes. The Oak tree farm link has clear pictures fir that x. It is the babies that are difficult to sex sometimes but you don’t do that until they are four weeks old. Until then, as mentioned above, they shouldn’t be handled or it could make the Mother cull them. This is an instinct if they fear the babies will be harmed so rather than have then eaten by a predator, they cull them themselves. But that can also happen even if you haven’t disturbed anything if the Mother is too young to know what to do.

It sounds like you now have two babies, which is manageable and when it is time to sex/separate the babies it will be easier as if there is any doubt you can just put them each in a cage on their own. I would say though that you still need pregnancy watch for the Mother as they can get pregnant again the day of giving birth - if the male was still in there. That is how robos breed like wildfire!

You’ll need four bin cages at the moment - the current cage plus 3 others. One for the adult male (who I guess already has a cage) and two more in case each baby needs their own cage. The reason the babies need separating by four weeks (I think - it’s on the Oak farm link) is so a male baby can’t make the Mother pregnant again. If both babies are definitely female at 4 weeks they can be left in with the Mother but if there is any doubt over sex then put that baby in a separate cage.
