I have some 5 week old kids that look ill. They are all hunched up, not playing, mostly standing still, or laying down. Some are shivering at times. I am not sure if it is because they are all eating more grain. Or because I ivomeced the does last night. Will ivomec effect the kids? While I was checking them out I found several of the kids have small crusty scabs on their skin. Could this be mange? Should I ivomec the kids? The kids look healthy enough otherwise. They are all thick and muscular looking.
