Our ewe lambs had not been handled much due to the owners circumstances and were to start with just brown blobs in whichever corner of the field was furthest away from any human they caught sight of. Did wonder how we could bucket train them as they had no idea that the bucket was anything to head for. However curiosity eventually got the better of them and within a few weeks they were coming when called. So even lambs that have had little contact with people, soon (in our experience) learn ..... may not be the case with older ewes.
Our local farmer said that it was best to get them used to taking food at a young age, not only for ease of handling, but so that they would readily take food as a matter of course during hard winters. He reckons they might otherwise behave like hill/mountain ewes who will starve rather than take hay etc. when brought down due to harsh weather. (Not sure how true this is

but he seems to know his stuff

) In fact the breeder of my ewes said they refused to eat the hay that he struggled to get to them when the ground was covered in snow for weeks on end.
