I've got a heifer who'll be 2 in October. She's currently over gettin' friendly with the bull. Nice brangus bull very pretty and stocky. I've got a small ewe flock so the process isn't completly unfamiliar, but what sort of care will she need, as far as vaccinations, nutrition, housing, etc. We've got a barn but it was used for hogs, so the pens are completley too smal, perfect for lambing jugs though . What size of a pen should she have. Any advice apreciated.
