Hi all, my ducks were attacked by dog this weekend and I've been having a hard time getting them antibiotics. I was able to find "duramycin-10" tetracyclide hydrochloride which they said was good for poultry but I want to be sure it's ok for the duck...I don't want to give them something to help them that may be potentially fatal! Also, it's suppoed to go in their water. Thank you!
