Hi all, hope you can help. I have introduced three new guinea pigs to my six free range guinea pigs, all female. Two have integrated very well but one has isolated herself away from the others and spends all her time in a separate hutch on her own. I have tried putting her back with the others but she just runs back. Should I just let her be or lock the hutch she runs too so she has to mingle. I don't like the idea of her being lonely on her own but she's just not interested in the other pigs.
