the first thing im gonna say is pigs dont smell,actually their very clean animals,also keep the ark clean and never mess in it,however pig pooo does smell and will only give you problems with immeadiate neighbours,in a built up area. DEFRA if you raise the correct paperwork and record movements etc you are unlikely ever to see defra other than the odd phone call just to see how you are running your livestock. If you ring defra they will set up all of it over the phone incuding your CPH number and all the paperwork that goes with it.............................good luck dont give up pigs are great ,think you might hear from kate shortly!!................................neil
