Recently I just got a new piggie for my other girl. One is around 2 months and the other is 6 months. Sometimes when they eat the older girl backs off when the younger one comes and she seems very very hesitant to approach the bowls when the younger one is eating there. Is this bullying? should I be concerned? Any tips in helping them bond? My cage is a 2x4 cc and I have two of everything. thank you
