They are brothers abd have always lived together. I made a mistake by letting an 8 month old unneutered male near their cage and they had a big fight. after that I seperated them (this was a week and a half ago). I have now brought all the rabbits into an outbuilding for the winter (not including new bun). They are having run time together and seem fine. Do I risk putting them back together for good, or at 16 weeks are they likely to fight again. My vet won't neuter til 5/6 months.
