I've done both as far as keeping the males in with the females with litters and taking them out. I currently take my males out when the females drop their litters or are otherwise visibly pregnant. I've not had any issues with males eating or hurting the litters, I just do it to give my females a break from being bred. For me personally, I've noticed that the litters tend to stay smaller and develop slower when the mom is immediately bred again by the male after having given birth (postpartum pregnancy). I have enough breeders that I can cycle my males through giving the .2 per tub a rotation off, so to speak, by having other females that I can pair with the males to allow the females that had delivered to raise their pups to weaning size while the other tubs of females are being bred and then vice versa, if that makes any sense at all, lol!

There's no hard or fast rule to say you can or can't, it just depends on your needs and your animals. If you have a male that's eating babies, I'd feed him off were it me, same for a female. I've had first time moms eat a litter and they get one more chance and if it continues, they're snake food. Figure out what you need as far as production and what size and then that will give you some idea as to whether or not you'd want to be breeding your females back-to-back on their litters. You'll wear them out a lot faster and they won't produce as long doing that, but it can be done. Try it both ways and see what you like better...it definitely adds to the hassle to have a separate tub to house the males when they aren't breeding but again, it works for me in my situation so all I could say is try it and see what works for you. Good luck!
