Hi Hazelwood
It is worrying i know, i'm sorry to hear you have problems too. Trouble is the lambs are not that noticeable until you lay hands on them. we would have suspected our ram but we've used him before with no problems for several years, but then we know we tested positive in the affected fields. so i can only assume this is the virus that causes this deformity in the lambs born alive, who appear normal at first.
We will creep ours too and hope they don't get worse as they grow. only time will tell.
