Little late with this, but just put a nose flap on them and forget about moving them, fences tore down, bawling, going off feed, sick, and just leave them with the mothers. And yes about 1 of 50 will figure out to turn his head sideways to suck, but it's a dang sight easier dealing with 1 than chasing 50. Put 'em in when working them and take 'em out when boostering. No extra work. I've left them in as long as 3 mos. and hav'nt had a single problem. Stress free.
