The Henry Milker is pretty much the only way I've ever milked our sheep. We have Babydoll Southdowns and a Finn-Babydoll cross; rather small sheep. I needed to collect colostrum for bottle babies last year and the Henry worked for that. Since it worked for milking colostrum from the sheep I kept with it and took those ewes' milk for about a month. I didn't use a stand. I straddled the sheep backwards at a hay feeding once per day, stooping to milk from the rear. It was a little rough on my back, but I was happy to have that precious sheeps' milk for the short time I collected it. Having larger sheep and a stand for them I suppose would be a much more productive approach in using the Henry Milker. I wasn't after large amounts of ewe's milk though. I made one small batch oh cheese out of pure ewe's milk, but froze most of it to blend with goat milk later in the season. I plan to do it again the same way this coming year, if time permits.
I use the Henry on our Nigerian Dwarf dairy goats mainly. I've been pretty happy with it as an economical alternative to a milking machine. I find it actually slower than hand milking, but easier on the hands.
