Okay, I had the vet out, to give my three pregnant does their BoSe injection, CD&T booster, ( she used Covexin 8) and just to establish a vet, client relationship. Since I am new to this and these will be my first kids I also thought it would be a good idea for her to just check out the moms to be and make they were in good condition. The problem is I mis calculated the due dates. I thought they were supposed to be due June 11 for the first one and then two, three days later the other two but that’s wrong. The first one should be due June 21 and the others June 23 or 24. I messed up and was going by wrong breeding dates. My Question is since the vet gave injections at 6-61/2 weeks out instead of 4 weeks should I revaccinate them with the CDT or do you think they will be good?
