I am not familiar with your breed, and I'm totally unfamiliar with wool sheep, but I would say that, since they are not dairy, they probably should not be as thin as you are describing.Is the amount of grain I'm feeding too much? I know that technically they don't necessarily need it. We've gotten them recently (maybe 4-6 weeks ago) and they've looked underweight* so that is why I have been keeping up with the grain. I've been hoping that getting them to a better pasture would be helpful in the weight department. But I didn't give them any grain today and I can hold off for another day or two, probably won't hurt.
*Underweight as in can feel pelvic bones easily and kind of sunken in around the pelvic area -- reminds me a little bit of a jersey cow look. Not emaciated or anything and cant feel ribs or anything like that. They are supposedly Awassi sheep and im not sure if this is just how the breed is. Just hard for me to tell with how the wool is coming in too.
Just reading now about the body condition score and would guess that they're 2.0-3.0.
