hey by the way, I’m sorry there was a yellow dot over the letter B in the picture of the liquid B complex. It’s just because when I did a search through my pictures, it searched for that word and then it put a box around it. Apparently, I didn’t notice the dot covers the letter B.
it says injectable, but we give it orally to ducks. if you can order some or pick some up right away at a tractor supply or other feed store may have it online at Amazon also. Hopefully Miss Lydia will be here soon with dosage information for your ducklings.
since you are giving peas ( or anything else other than their feed) they need grit available, they will take what they need from a side dish. I would use the durVet liquid b complex. not sure how much for duckling though for a grown duck I give one ML per day if they need it.
