My female BN has gotten a rounded belly on her, and I'm wondering if she could be pregnate? The only possiable male that she is in with if my rubbermouth, unless one of the two albino babies is male, but their too young for bristles. I don't know how to tell the difference between the sexes with rubbermouths, so I'm not sure if it's male or female. If it's possiable for them to crossbreed, could she have bred with "him"? Honestly I don't know if her weight gain is from fat or the other. If there's a chance she is bred, what should I do. I definately wasn't expecting this possiability.
