Thanks Guys,
Brilliant help, we'll ring Alpha. Re: the previous owners, I am sure they acted the way they were told, perhaps things have changed recently but Trading Standards did mention that we may be told to register all the animals in the same register which I thought may be wrong but ties in with the holding register passed onto us.
Looks like the pigs may be on their way soon (after I have sorted out the fencing of course!)
Thanks again,
Mickey
