I know my ducks been given amoxicillin before just not in tablet form
My girl is hard to get a pill into so now I crush it up and add a little colloidal silver in a syringe
You could use water if you do struggle
I only add 1 ml of liquid
@Miss Lydia
I have tagged a member who can maybe give advice. With swelling and hot to the touch I would think infection as well
Hopefully she gets better soon
