My go into grow out tanks at 3 weeks on the dot. Make sure water bottle has a light weight Ball so they can drink. If you do not pull them the next litter will die.
As some will mention pulling males this is NOT a option with ASF's. They will fight/kill the male when re-introduced. Your best breeding will be 3-4 litters tops from each female and then you need to feed them off, after three or four litters they will produce only 5 to 8 pup litters. I start growing pups from the 2nd litter to replace the mothers after their 4th.
