Ah ok, this is only our second batch of weaners. The first time, the seller tagged them as we loaded them into the trailer, and we just sent them to slaughter using those numbers. The EAML database was updated automatically as the movement to the abattoir was received, and all was well - I thought!
I therefore thought that was just what you were supposed to do, so again asked for them to be tagged this time at point of sale. It made sense to me at the time because that's what you do for sheep, and what sort of maniac would invent a different system for pigs?
[member=24672]harmony[/member] - So say I buy three new tags with my own herd number on them, and tag, how do I change the EAML records to show this? Surely I'm going to end up with three (old tag) pigs still shown as resident on my holding, and three more with new numbers that appeared from nowhere?
