I bought one of these in Hawick during our trip to Scotland in May. The local feed and grain store had any number of excellent products and gadgets for caring for and saving the lives of sheep which are not available here. Goodness knows why. You would attach this to the end of a pole 4′-6′ long (1.2-1.8m) and use it to catch ‘loose’ sheep. When you only want one out of a mob (eg it has wire caught up in its fleece; it is limping; its lamb is ‘flat’ so both need shedding…) it should prove a real boon.It is available online http://www.coxagri.com/breeding-equipment/crooks/shepherds-crook-head-aluminium
Also available above are these ‘gambrels’ used for restraining sheep (eg ewes giving birth). I have had one of these in my ‘lambing bag’ for 30+ years. I can’t imagine how many ewes/lambs it has helped save the lives of:
The large space in the middle goes over the neck then you lift the two front legs into the other two spaces. The string is never needed. You can use a piece of cord of the appropriate length in each end of which you have tied an overhand knot. You place the middle of the cord over the neck (as above) and pull the front legs through the loops.
The beauty of this arrangement is that it costs nothing and slips into your pocket.
