we had to give our ducks shots for, get this, lead poisoning. our son spilled some old led shot my husband used to fill shotgun shells with and we had to take ducks in and then put on shots... never put the needle in your teeth I almost did that out of instinct trying to hold the wiggling duck...they had warned us about this and that is what saved me... I will hold off putting her down and will get this antibiotic if possible in the am... and give her a shot asap, how much do I give her again? I am feeling so overwhelmed and can not tell you how much I appreciate all the fellowship and help I get at this website.
