Is it not a sign of twin lamb diease? Maybe someone else had heard that before? Where you feeding them?

Hi, Was told before it was down to selenium deficiency among other things I can't recall

What % of ewes are lambing with this?

Over half the twins have come this way one ewe had twin lamb disease and had two matching lambs there is buckets of minerals in with them since they went in the first week of jan getting pound and a half a day approx

I'd be blaming an incident in early pregnancy...first six weeks
Chased with dogs/ short of feed.
Greysides might comment, we might get one in a hundred that way

we had that a few years ago also, low selenium area round here...
we blamed that and young ewes?

The only explanation I'm aware of for unequal twins is where they start off as triplets but one dies before the placentas have finished developing. The extra available space allows one lamb to expand it's attachment area and grow bigger due to the better nutrition. You might expect a few to happen this way, over that it sounds odd.
