I am going to worm all the kids next week that will be 6 weeks old . I was wondering what most use for the 1st time . I have already treated them with sulmet for coccidia prevention now that they are eating hay and picking on the ground at the new green grass.They will get their CDT shot tommorrow since they are over a month now . I like to leave time between each dirrerent thing that needs to be done . So what is the best to start with ?
