Guinea pig problem

Hey, My guinea pig had two babies about a month ago, one male, one female. We sold the male but since then the mother has had a nother litter of 4 guinea pigs which the first female is attacking and the mother is attacking this one in return, why is this???

thsi is because she is protecting the smallest and most weakest pigs. You will probably need to sperate the older one from is mother as its acting like this due to jelousy

thank you we have separated it now but is there any way we can make them all get on together??
