I am getting ready to move the girls to the larger pen, all that's left its to get 1 section of fence up and the gate. By the time I get that done the grass will be green, thick, and about 8" tall. I have been hand cutting a wheel barrow full and throwing it to them in their smaller pen to help condition their rumens for the move. Is there anything else I can do to help ensure they don't bloat when moved? The smaller pen is pretty much grassless as they think they're sheep.
