I have 2 breeding groups of asf. I have 4 adult females in one tank that had a litter of 9. After feeding a all males but 1 I have 1. wean .4 wean and .4 adults. In the other group i have 1.4 sub adults. My question is what is the best way to introduce the male from group 2 to the females of group 1. Group 1 is almost at retirement age and i want to get at least 1 litter out of them because the weans need a few mor months. Itried it before and there was some fighting.Any input on what i should do?
