[Jacob-list] sick lambs--any suggestions?

[melody]

.  One of my sister's yearling ewes had twins last Thursday, and wouldn't
take them.  After holding the ewe so they could get the colostrum through
the first day, she has been bottle feeding with Purina milk replacer.  They
have been doing well, but this morning began to act as though they were in
pain, just standing around humped up.  They acted as though their hind legs
are weak or painful, too.  Now their front legs are showing the same
weakness.  Any ideas what this could be, or what to do?
