I have two pairs of buns that live side by side in sheds with attached runs. The runs are joined together with a wire mesh partition. Mist and Smoke have lived together for about two years, Barney and Bella for a couple of months and so have lived next to each other for a couple of months. In this time they have all lived quite happily with no chasing up and down the wire. Sometimes they all sit together in a little group. Sould I have a go at bonding them or would I be better to leave them as they are? I wouldn't want to risk upsetting the existing bonds. It would be nice to have them as a group of four (we could take out the partition and they would have loads of space). Has anyone had experience of bonding two pairs? Is the bonding of two pairs usually successful or are they best left as pairs? What are your opinions please?
