Hi Harmony, thanks for your reply, the two who have had litters are housed together at the moment and the third is in the next stable across at the but was with them until about a week before farrowing. I intend to reintroduce them in a large shed before putting them outside. (They were all served at the same time and were living together at that point but only two held unfortunately).
I may introduce a boar if I can find one for loan but if not I would potentially use AI as I did the first time round. So I’d initially be looking at space requirements for three with the potential to extend the area for fourth if needed.
