I have ladies shears, Mr F has big ones which I can't use. The place to look at what's on offer is at the agricultural store. I don't know what's available in Peebles........
We usually shear in June and sometimes into July. We do just a few at a time, out in the field. We don't have a big gather to do them all at once, just pick out a few easy to catch ewes, then round up the last few uncatcheables at the end. The tups come in like babies, so no problem to do them. I can let you know closer to the time which are likely days for shearing, but it also depends on how Mr F is on any one day (long story)
For your draggly lads (presumably last year born, so technically hoggs), pull off the trailing bits by hand, otherwise you have fleece all over the pasture. Make sure they are dagged too to keep the flies away until shearing time.
