As previously said, no problem if they're just for you
But I can see why there's so much confusion - when we moved back down here with ours, our lovely AH man in Scotland advised us that there was no problem - I had already planned-in our stops for watering & checking, along with drink & pee breaks for us & the dogs
I carried the scoteid form with us, as I had young home-bred gilts with us that were not tagged, logged back in when we (finally

) got here - all ok
But ...
when I logged with eaml2 I got a call from AH down here giving me a right earful about not having a registered herd number (didn't realise our Scottish one was no good in Wales

) & did I know that I should have taken a "trailer driving test" ? - ha ha I said - flattery won't work with me - I've held a driving licence long enough not to need to do it
