Thanx A&A, just hope the boys behave like gents - they should do as they are so placid and chilled. They are blood brothers and there has never been any aggression between them, even when they were both put to the same doe before they were 'done' neither of them were moody with the other afterwards.
I'm going to set the girls up im my 6x4 run with a hutch to start with and then put a fence up round my patio.
I'll let them out to meet once that's done but it looks like it might cost a bit to get the fence done!
