If the Guinea Pigs are in the same enclosure together (this answer assumes that they are) then separate them. If you only have Guinea Pig enclosure, consider buying a divider panel (however, make sure each Guinea Pig still has enough room). If you currently don't have a divider panel, a wall made from cardboard should do the trick. However, the Guinea Pigs may chew on and destroy the cardboard wall, so it's best to get a divider panel as soon as you can. I hope this answers your question.
