A day is ok once the male has successfully crossed it. If the male is calm you may leave the female for up to a month. With that you are asured of a successful crossing.
What if after leaving the male and female for months before separating and the female refuse to give birth,what should I do?And how Will I know whether the female is pregnant or not.
When you leave a female with a male for a month and there was no pregnancy. Change the male. And give another female to the old male. We want to know where the problem is coming from.
