When i bonded 5 sows to 1 boar i think i did it in a 4 x 4 C & C.
I watch for about half an hour up to an hour & if there's been no continuous aggression i put them where they are going to live.
Positives would be no continual chasing/nipping (ie no persecution of one single pig). All pigs should be allowed to exhibit normal behaviour, they should all be free to move where they wish, eat & drink without fear of being chased away. Bullying in pigs is as bad, if not worse, than actual physical fights.
Sows may chase, mount & nip & the pig being chased/nipped will wheek but generally this does calm down quite quickly tho' you may have an occasional spat if say a baby/younger sow were to be in a certain place that the head sow wanted to be in but they catch on quickly & generally move out the way when they see her coming.
Ideally you want to see all pigs settled, wether they be together or dotted about.
On rare occasions you can get one who won't have any other pigs or won't have one in particular.
I have only had this once in all my bondings over the past 6 years & the pig in question was a right mardy mare who loved only her boar & would go for every other pig near her & she meant it but she did make aware of what she would do.
As soon as i saw her narrow her eyes on her chosen pig i'd distract her (this was out in the run, she didn't live with a group). She was an absolute s*d but oh how i loved her
