If i was standing there I could not leave that poor duck there. Looks like some one has plucked it. your decision just giving my 2 cents. I'd take it home clean it up give it some good feed fresh water with a tiny bit of ACV in it and watch it for a day or 2, if it doesn't show improvement in breathing then I'd get an oral antibiotic and start giving that to it. A nice warm bath does it even have a bowl deep enough to wash it's face?I'm here now and it actually looks much better than it did last week, however it's still breathing heavily, wheezing and not moving around much. Its eyes do look a little brighter. What do you guys think...?
Actually, since I sent in a complaint about conditions here - they may have brushed me off, but it does look like they've cleaned up a bit. Not much, but a little.
