I needed some white wool for blending with our black for new rovings so I went over to one of the big range flock operations during shearing to buy some wool.
The big flocks hire large crews. This crew had 13 shearing stations and the sheep go up the inside, get shorn and the wool drops out the back and the sheep climb out the front. This particular flock was going to take 2 full days to get shorn. They have about 2500 ewes.
