With the white ewes I am considering possibly options if they lamb close together. As the ewes do not have tags or any notable differentiation other than the younger looking two and the older looking two. I was really hit with this when I wormed them and had to have hands on the next ewe as not to double dose any of the white ewes...
Thinking that I will be banding tails will help. If one lambs in the morning I will hopefully have checked them and banded tails, taken weights, etc. before the next one goes. So the newer lambs won't have tails banded yet.
However after the first couple days if I end up with many white lambs I will have to rely on the lambs going to the correct ewes. I was planning to put in ear tags at a couple days old because newborn lamb ears are just so.. new and soft and tiny.. I hate the idea of putting tags in their tiny ears and having one rip out

I know that may happen but I want to try and avoid it.
I hate marking crayons but I was thinking if I got one I could do something like mark the first set with crayon mark on top of the head, then the next mark on the tails, the next on front legs, the next on back legs,... And I would make note of it in my notebook I have added to the lambing kit bin. This will help me to keep track of the lambs until I tag ears and then I can keep sort of track of the white ewes that way too. In case any have any sort of problem I can mark it as whichever number lambs mom. That will also be good to watch for in keeper ewes if any have problems I will know which ewe line is culprit.
Am I a little overboard with the ear tagging? I was thinking definitely before a week old.
