Question need help
so we bought two chinchilla's (we havent had them for 3 months yet) one male one female. Everything seemed fine they looked like they were getting along great till one day we come home and the female gave birth to a baby ( its a week old). So we are thinking one its not the males baby and it was pregnant when we got it. So when we saw the baby we read up online that we needed to separate the male and female for least 5 days ( we did that ) we put them back together and hoping everything would be good but later on today i see the female chasing the male and looks like shes trying to fight him. Is this normal after birthday, should we separate them again? Im hoping they will get along but not sure what to do. Anyone have ideas?
