Hiya Emily
Welcome the forum!!
I hope you enjoy your time here
I think you have come to the right place with all those beautiful hammies
All of your hamsters are beautiful, and i love the little place you have for Smudge - that is so sweet
Ruby is looking lovely and it is great that you have rescued her
As you have already found out, male babies should really be removed from the mother and female babies at 4 weeks - but obviously your aunt didnt know, and she has been split now - so the only thing you can do is look after her and hope for the best
It wont hurt to feed her little extras each day - she will probably need them even if she isnt pregnant just to help her out with getting back into shape after rearing the babies
You can give her boiled egg, scrambled egg, plain cooked chicken, bits of pasta, ready brek etc.
All of this will help her if she does have a second litter too
Good Luck and keep us posted
