Hatty,
Sorry we are a way from you - you could buy our book !
Mangalitza's are not a first timer's pig. By all means get some for a second lot.
They are pushy, prick eared - see all , ours ran at us every time we went in and was quite bitey until tamed. Now she is lovely, but it takes a little knowledge to know how to handle. Bit like giving a porsche to a 17 year old - can be done, and chances are they may not kill themselves, but probably better to buy the Ford Focus and let them get used to it!
They have some differences to other rarebreeds:
They don't grow very big
They are very slow growing
They produce a much fattier meat, which is great for charcuterie, but not so good for ordimnary joints, chops etc.
They are very hairy, which the abattoirs don't like.
