I have a hen with a rather deep gouge in her side and some rough breathing. I was recommended teramyacin, but my local TSC doesn't carry it - only liquid duramyacin 72-200. I can not do injections - can the liquid go in her drinking water?? If so, what would be the recommended amount per gallon? I have already treated the wound as best I can but definitely want to eliminate infection. Would definitely appreciate any responses - I want to treat her ASAP!!
