I sheared all my own sheep apart from some of the lambed ewes in 2018. (Several wethers and other fleece sheep, and about 12 hoggs.) I did them standing up (them and me), in a small pen, largely unrestrained. I just had to pop them on their bums to do underneath, and some of them didn't like their legs being clipped standing free. Hand shears, of course. I took off chunks as I went, sorting into "spinnable" and "dirty/not nice", and white and colours as I went - which is fine for me to use but meant I didn't get whole fleeces to sell.
I did one to three a day over a period.
I thoroughly enjoyed the time with the sheep, and the insights into them and their fleece that it gave me. I will definitely be happy to do some of them again. Didn't have the spare time last year, but should be able to do some this year.
