Sounds like they were overfed so the lambs grew too large. So sad that they had to be destroyed
I'm feeling very glum myself at the mo - not only is my wee fleece flock off to a disastrous start (3 dead lambs, a sick shearling and a dead shearling), but the shearling who's died was one I bought from someone who wanted good homes for 5 crossbred gimmers... I shall hang fire on telling her, when hopefully I shall have better news from the other 4 to soften the blow.
Meanwhile, I have a fostered lamb now orphaned and on the bottle
I split a pair of twins to give my now deceased shearling a lamb to love, which she did, unfortunately not for long
And don't ask me why - just 'one of those things', sometimes you get some aborted / predeceased lambs at the beginning of lambing.
I've just been very unlucky to have 2 of my 9 fleece sheep be 2 of them - there was one in another batch (of commercials) yesterday, too, so it's not just my little flock.
I have in the past taken lamb and placenta in to the labs, but they always say it's not fresh enough, and/or there's not enough placenta, to tell anything. So unless I get a fresh lamb and a good bit of placenta with, I shan't bother with that again.
Sorry, didn't mean to threadjack - just I had been feeling that I wasn't looking forward to telling the previous owner of this nice little shearling that she'd died in my care.
