On arrival at my sheep field at about 7.30 am last week, twin Jacob ram lambs had been born and mum had managed on her own ok. The lambs were up, had been licked dry etc., and although the smaller of the two was slightly weaker than the other, he was alright. The puzzle was that both of them appeared to have had the end of their tail chewed down to raw flesh with the skin hanging off in threads. I dipped the exposed ends in iodine and the lambs seemed none the worse. Anybody else experienced this? Was it rats, crows, magpies or some other predator? I can't see it being caused during birth or by the ewe's attention. Mystery.
