Pick them up and stand on the bathroom scales, then subtract your weight.  I hope you're a strong lad :roflanim:
I think the aim is 38kg which will give you (very roughly) approx 18kg of meat.  But if it is for your own use, you can send them when it suits you, you will get roughly half the weight back as meat.. 
There was a post where SITN explained the weights required for commercial lamb.

Gosh Ed, you've only just got them and you are already talking about sending them off  ;D


For lambs we use bathroom scales. Weigh yourself and then get on the scales holding a lamb. Not quite so easy to do that with a full grown ewe though. You might be able to rig up a spring scale for that.

The golden liveweight is 40-42kg for a commercial carcass, any more than that and it is penalised for being too fat.

We send ours off and they normally come back around 10.5-13.5kg per half, so 21-27kg deadweight, roughly 42-53kg liveweight. But the KO % differs for different breeds, normally for a commercial carcass it's about 50% for primitives it's a bit less. Also worth noting you can let them get a big bigger (not fatter) if they are for private kill, our lambs would be far too heavy for commercial slaughter but we sell them butchered privately... the butcher is always amazed how they grow big but don't go overfat... I have no answer to that aside from they are not forced and have very good grass :)

We don't have scales but I go on how they feel. We've got 4 going off in mid August who feel a lot different to the others that aren't quite ready yet.

This is a very good guide which tells you what to feel for-

And just as a visual aid, these are the first 4 of our lambs that will be going off in August-

As does this farmers weekly article- I found this very helpful

As said, depends what you want, in general here, commercial lambs are finished between 39.5 and 42. But there is a big export trade for lighter lambs etc, so depends on market. Home kill, its what you fancy for yourself.
