If her stitches are healing well and not seeping then you should be able to put her into an enclosed run. I just ensured that Honey was kept away from the shrub border as I didn't want her jumping over branches or anything that could catch her stitches.
Re, the bonding question - a difficult one as bonds vary so much - Honey was back with Hobo the day after her op, although they were already a pair. I know that Harmony was introduced to Azlan about a week after her op but I would watch them like a hawk and if he tries to mount her or she starts frantically running around or leaping to get away from him then I would wait another few weeks. If they are happy to sniff, nip etc. then persevere.
