Putting all the horses into one paddock for two nights

Some cattle need to be moved on the property, so I've put the horses into one paddock. I tried Penny in a separate paddock on her own and she didn't settle. So I popped her in with the rest of the herd.
This video records the minutes after putting her in, to check she wasn't hunted by Tuppy (who has been known to do this). It was all calm and again when I checked later.
