Hi Justine,
I will definately sell these two that i kept for you then!! lol!
Good Luck with the babies!
Unfortunately, it is extremely difficult to sex Roborovskis properly and i have had many which have surprised me and turned out to be boys, when i thought they were girls.
There are many photos showing male and female Roborovskis which are over 4 months old and it is very easy to tell which one is which, but the problem is when they are under 4 months old!!
I find it very difficult to sex them at an early age, even though i have been doing for quite a while now, and i sometimes end up keeping them until they are 3 or 4 months old, just to be sure of the sex!
Males seem to 'hide' the fact that they are male and sometimes wont actually 'show' themselves to be male unless they have to, such as if they get put in with an older male - then you will see the change almost immediately, the testicles seem to inflame and within a few hours the scent mark will be yellow!!
They are fascinating creatures!!
