I do like the GOS, and saddle backs, but have been told the Tammy's are superb eating, I don't mind them been slower growing, except it gives the Mrs longer to name them and make pets !Warm and dry wouldn't be a problem, I have lots of barns spare, I was thinking I may well end up building a pole barn in the field they are going anyway, 6 - 7 foot tall, 30 x12, enclosed on 3 sides with a roof and open front, would be handy for keeping all sorts in.
May even end up with a farrowing pen if it all goes good
