How many females do you have? 2?
I would suggest you get at least 2 more as males will constantly harass females, sometimes even to the point of death through stress. I usually recommend 3:1 Females to males but usually 2:1 will work. Depends on how badly the males want it
Can you get me a picture of the females? I'll be able to tell you if they were close to giving birth or not better with a picture
