I'm going to be buying my first two lambs soon & have chosen one ewe lamb already, they're Katahdins. I'm looking at another lamb that is a twin ewe lamb that was born weighing only 3.5 lbs, the other ram twin weighed 5.5 pounds. The breeder says she is doing very well & going out to the pasture with the mom & all. So far she looks to be doing well despite her small size. My question is do small twin lambs that are born small like that usually catch up in size & do OK? I really like the coloring of this little ewe & if she is healthy despite her size I would really like to get her. I won't be getting either lamb until they're weaned, so this one does have time to do some growing & filling out. Any advice on this would be greatly appreciated since I'm new to sheep.
