I noticed this morning that #701, the first (surviving) lamb born on the farm, is getting very close to her mother’s size.  The ewe probably has 4 inches of fleece bulking her up, while the lamb has perhaps an inch, so the size difference is smaller than it appears.  I don’t know enough to claim that this is an exceptionally fast-growing lamb, but I’m amazed that the calories from grass and a little bit of corn can produce such a large creature in four months.
