2 litters in one tub bad idea?

well the other one did drop 8 2 days later.. some were looking kinda runtish so i tried moving them to separate bowls.. they diddnt like this idea so they moved them back lol. when should i move the babies to their own tub? And should i keep males from females? I'm all kinda new to this not sure how on i keep them sorted. Or do i just keep all the kids away from the breeding pair and let what happens happens to the new females?

thank you! so far all are living and doing well. I had read that they get very aggressive with babies around but so far mine have been pretty ok about my handling and cleaning since they decided to have them on cleaning day. I heard some squeaking and was afraid there was some baby eating going on but after watching for a minute I saw it was one of the females moving the newer pinks to the top of the pile
