Hiya, try to get the tags so there is enough room for the ear to grow, but not soooo close to the edge that it will easily catch on the first twig. I do tend to leave the tagging until quite a bit later for a number of reasons.
1. the lambs have time to grow a bit
2. less chance of losses/ ear ripping before going to market/slaughter/ etc
3. oportunity to health/ feet/ fly check later at the same time
and cos i am sentimental and feel that the wee souls have just had their tails done,and their bosies done !!!
How old are your lambs? and what are you doing with them and when?
