Entire batch of only female cons?

[Loshmitchell101]

Hello,
So i have the black convicts,
Weve raised our last batch of babies to adults,
12 out of 13 are all females.
Is this a common thing?

convicts should have more then just 13 babies. and if the babies died or were eaten that could be a reason for the lack of males in the batch. maybe the males just happened to die. survival of the fittest.
