I've decided to give rat breeding a shot so I built a rack and got some adults. I have 3 groups of 3, 1m 2f each. I thought they could be left together to raise the pups but I got my first litter and a day later they were completely gone so someone ate them. The mother made a nice big nest out of the substrate and had them all together nursing when I saw them. Then the next morning they were all just gone. I asked my breeder and he said I might want to try separating the new mother and pups next time. I'm wondering if removing the male is also an option. I really didn't plan on having to relocate females or males every time I have babies, I really just don't have enough room which is why removing the male may be a better idea and then let the two females raise their litters until I'm ready to breed them again, it would at least save some space. I only have one extra tub in the rack for grow outs and then two separate containers I could use for either a male or mother and pups. I'd just like to get a plan together before I get my next litter, I'd be pretty upset if I lost another one.
