I introduced my male back in with two of my females. They smelled each other, and do what rats do....Well sometime later they started breeding... after each "service"( I don't know...lol) the male would o over groom his parts, then sprall out on the floor, then about a minute later, find the closest female and start again...well it was only one female that was actually getting bred...the other wasn't for some reason( she might not be in heat?) I guess im asking if this is all normal behavior? I have only paired them up once before my other litters, and never witnessed breeding, but I got 3 litters.
