Probiotics for one duck

[Jenbirdee]

I have one duck on an antibiotic (tylan) and want to give a probiotic after her week of tylan is done. I have probios powder form to add to feed but i dont want to use it up that way cuz all 12 ducks and 2 chickens will be eating it too and its expensive
So I want to figure out how to give it to just the one duck without separating her from the flock (again)
i guess maybe i mix some probios powder with water and use syringe down the throat method? If I can avoid that it be nice. Is there like a little chewable probiotic treat that a duck might like?

Do you have dissolvable pill capsules? I think you can buy them on Amazon. I've used that in the past to give ducks powdered medication. I find it much easier than a syringe and it seems safer because I can feel where everything is going.
Alternately you could withhold food overnight, feed them in the morning, and pull that duck into a carrier for an individual breakfast with powder mixed in.
