UPDATE: So far 2 female rats have had their babies and they all died. What i noticed in the second rat, that was also present in the first rat was premature babies. In the first rat i thought they were torsos, but i took a closer look at the second rats and they were tiny rats all curled up not fully developed.
The rats were in different cages, the only thing i can think of was ising cheap rat food from the local feed store, i had to use because i was waiting for the mazuri to come in.
