Salgen is not a jab Dave it's a freeze dried (hope I got that right) in a bottle, you add say 17/20 mls of water to dissolve the contents give it a good shake & it's ready to go. 1 drop in the beak for a yb while in the nest or 0.3 when they are about month old or just weaned.
This is for Salmonella easy to use & your not breaking the skin or hitting muscle in the neck.
