Thank you for all your advice and research. I am someone who takes my animals to the vet as soon as I know something is wrong and I don't know what it is. We are first time duck "parents" so when we knew something was wrong with our little guy we took him in. I had a very difficult time finding a vet that would even see him. The vet has been calling to monitor his progress, at this point is has no other treatment she can offer him. When she examined him and put him on the Amoxicillin, she said that legally that is about all she can give him because he is considered a "meat animal" (even tho she knows we will not be eating him). I'm not sure if this is true for everywhere or just where we are located. My bf has been doing all the research and pretty much everything to help this little guy. We are just trying to give him a chance at life. If he does not improve, we have a plan in place if have to humane euthanize him which includes have a necropsy performed. We want to make sure that our other babies don't get this and possibly help someone else if they find themselves in this unfortunate situation. Again, thank you everyone who has offered advice, whether we attempted your suggestions or not we appreciate everyone taking this time to research things and post info so quickly.
