We name all ours, it's easier to say a name than try to describe a specific animal when OH or children need a specific instruction about one in particular.
This.
Although with 300-ish breeding ewes we can't name
all the lambs or even all their mothers, but most of the bottle-reared ones and a few other distinctive ones get named.
Anything grand-nephew names is likely to be a friend of Thomas the Tank Engine - we all loved his choice of 'Diesel' for the runty - but very fit and full-of-life - grey Shetland x tup lamb.
Names are often descriptive - 'Pan' has one black eye (half a Panda); 'Green Spot' was marked so we'd know which lamb to take back out when he was used to help drink out an overful udder; 'Jacket' still has his on so we can tell him from 'Black Nose' and friends; 'Stinky Mouth' has a bad case of orf and has to live on her own till it clears up - she drinks Jersey milk as the lamb milk really stings on broken flesh; 'Shy Girl' wouldn't drink if any other lambs were watching (she's getting over it now); one year we had 'Snotter' who recovered, though with residual problems

, from pneumonia; and so on.
My favourite, I think, remains, a teeny little Swaledale ewe lamb on the moorland farm. She needed topping up at first while her first-time mum came into her milk. I named her Violet Elizabeth for the racket she would make until her needs were met - and Violet Elizabeth, in full, she remained all her life.
