Can a ‘herd’ of 22 of them sustain a family of six?? Yeah, but only if all six are vegetarians. Gotta save Mother Erf, ya’know.
Guinea pig daddys make good daddies and can stay with the family, but you have to remove him as soon as the babies are born cause the female can mate 24 hours after giving birth....after a week, daddy can go back to the family...
