Two of the bull calves we had born in the blizzard 3 weeks ago didn’t get banded.  One lost its mom to a prolapse the other got pulled because it was CHILLED.  Now they are a heavy 3 weeks old do they need a tetanus shot if I slip a Cherrios band on them?  They are inside on straw.  Newborns we just pin a band.  My goal is too normally band in the first 36 hours.
