I was recently given a duck, that came with some problems from neglect. Appearently it was given to a teen from a future farmers of america thing and fed it nothing but bread and left it to sit in it's own feces. Needless to say it developed ulcers on it's legs, one becoming infected. He also developed niacin deficiency and lost all function of his legs. I have been feeding him correctly and giving him niacin supplements, and he's regained function of his left leg. However his right leg is inflamed at the foot joint, and can't move that hole leg (I've been doing messages and roms with his les). I was told to give him tylan, in very small doses. I have been doing this for nigh on 6 days, yet nothing. Was then told to use baby aspirin, so I've just started giving him baby aspirin to knock off the inflammation. What should I do differently at this point? The end goal is to raise a meat bird, I can't have an unhealthy duck here. Also, what should I be careful regarding antibiotics use on meat birds.
