Good input.  I just know that there's several folks out there doing it, but didn't think about that aspect of it.  Guess if you ran light enough numbers, they'd have roaming room, but then your ROI on your building is hurt... I wonder, if you held them under roof during the summer and fall, and cut most of the pasture for hay, and then turned them out after 2nd cutting grew back out some, let them eat grass until it goes dormant, feed them outside most of the winter and then move them inside prior to calving and take them out at weaning and feed the weaners in the barn?  Just thinking of options for more head per total acres of ground.
