My 5 week old 1.5 lb rouen duck has been injured severely on his leg and web. Today I noticed fever in his leg, so now I'm sure he needs antibiotics, but I don't know where I should inject them. Could someone please give me instructions? Also, I think that judging by his weight he should be given 1cc of Norocillin (penicillin G procaine) daily for 7 days. Please share your thoughts.
