My kids have always raised bum lambs.
What are bum lambs, you ask?
These are orphan lambs that are bottle-fed. Oftentimes a ewe (female sheep) will die or will not have enough milk to raise her lamb(s) and so the lamb is taken and fed by hand. These are a few of the bum lambs that my son and daughter-in-love are raising this spring. The woolies were born in March and are really getting some bloom on them (healthy growth).
