I have recently adopted another guinea pig for my pig Arthur who was left alone after his brother passed away, it’s only been 4 days since his passing and only 1 day since I adopted the New Guinea pig. They seemed to be doing pretty well with the introduction process until I got home tonight and saw that the New Guinea pig has a few bites on his face. Nothing horrible but it doesn’t look great either. They haven’t had any Huge fights they just end up nipping each other in the face. Is this normal behavior for two males during introductions or should I seperate them?
