Happy to say that there were no problems, they took a little while to even notice each other as they have so much room. All 5 slept in the ark the first night, osbs in one corner and saddlebacks in another, this morning it was just a pile of pigs all lying together, doing as suggested and putting feed in a long line so no fighting there either.
Will post some pictures when this fog clears enough to get some decent ones.
Oh and Robert got my feed from East Coast Viners, very impressed by the service.
