Whats the prevalence of Rat mothers being a bad mom. I had one drop a litter and by the second day she had let 7 of them die. Took the other 6 and dropped them in with the other tub with a litter that dropped to day after. They all seem to be doing fine now.
I dont know when to pull mom and babies, and my friend says he doesnt bother. Should I pull Mom and babies of the next litter and separate into a separate tub and see what I get.
