I have got some weaners which I will be selling at 8 weeks old. Do I need to put the ear tags in at this age? I have bought weaners in the past at this age and they have never had any tags, so I put the metal tags in just before they go to the abattoir.
I am sure they should have tags at whatever age but would just like to find out if they do have to? I'd be glad of any advice.
