Those are great resources, j & g 

Fig 3 is exactly - and I mean exactly - the setup we had on the moorland farm - and I couldn't better it.  We handled all 530 ewes through that setup many many times.  Once the dogs were used to it you could manage it on your own, too, although of course it was always helpful to have another human to help.

Brilliant - now I just need to superimpose these ideas onto the space I have earmarked - particularly useful J and G were the diagrams of unsuccessful forcing pen shapes (I was going for one of them!!!).  Many thanks, F.  I will take pics when finished (dont hold your breath - this may take a few months!)
