[Backinwellies]

Can do as soon as umbilical is dry and lamb seems lively .... about 24 hrs. Delay for less lively lamb.   If you are castrating too then do at same time.    If testcles are too small at that time then leave both tail and testicles for a few days (max 7) .... long tail means entire lamb (no chance of forgetting an uncastrated lamb!)
