i found a IM cd/t shot for my goats (finnally!) and i need to know if 16 ga x 1/2" needle is appropriate for 9 week olds. also, how should i restrain them for the shot? the others i tie their faces into the fence, but this is not appropriate for the babies. when they were little i used to face them toward me and lift thier back legs off the ground with one hand, then stab with the other, but i have a feeling that they will give alot more of a fuss now.
