Just been refreshing my memory
Best Bonding Tips?
So I take it you now have three set-ups? One for Blossom, one for Jaffa Cake and one for the two boars?
Blossom had quite a go at Jaffa Cake and they won't go back together right?
It doesn't necessarily mean that Blossom is an unsociable piggy.
I'll be honest, the plan to put your boars in with Jaffa Cake and add a couple more sows scares the heck out of me! No offence, and I do understand how having a happy herd sharing all that space appeals to you.
If you are going to get your boars neutered then it may be safer long-term to see if your girls will accept a boar each. There's no garuntees on that. I have a sweet-natured and calm boar Freddie, but he naturally thinks that he is immediately in charge when it comes to meeting females (then he calms down and is gentle and sweet). I believe that is normal. Anyhow, I have had two sows who loved/love him, and two who have violently rejected him.
From the way I can make out your options (and I may have got your situation wrong, if so please forgive me), your preferred scenario would to have two happy boars and three sows all getting along and enjoying the space. I still can't see it happening for any length of time, even though they have lived in the communal big mixed group before you rescued them. Yours would be a complex and precarious arrangement that could come to blows at any moment. If there's tension in a herd any one of them can 'snap', boar or sows, and yours is likely to be tense with two boars in the mix.
May I ask about Blossom? She will still need her own set-up.
The way I see it Blossom and Jaffa don't mix, so there will always be two set-ups (one for Blossom) even IF the two boars and all other sows get on great together. Why not see if each boar can become the head of his own herd, starting with the two girls you have? That way none of them will be lonely if it works. Be aware, each sow you introduce needs to accept the boar for it to work.
If one of the sows rejects her boar then you're back to three set-ups which ever route you go down.
If you are wanting as few set-ups as possible then trying to pair them with one boar each is the most likely to work to have two set-ups. A nice neat split of your shed may work out really well and both pairs will have lots of space, and resolves the issue of both of your sows currently living on their own. Buying two extra sows in the hope of creating one large herd in there is likely to result in a split, and it may be harder to end up with two set-ups, as it relies on all four sows wanting to live in a mixed group, if that makes sense?. You may be back to three set-ups, with one or more still on their own.
