Hello wise duck gurus.... I am a newbie who rescued a newborn mallard duck 8 weeks ago. All has been going well until 5 days ago. I let "Henry" swim in my tub (normal evening routine) and when I took him out he couldn't walk. He seemed fine otherwise and was chipper and hungry. I read that it might be a vitamin deficiency so I went out at midnight in search of brewers yeast. I didn't find any but another site had recommended niacin so I picked some of that up. Fed him a bit of that but the next morning he was the same. Brought him to the vet the next day (where he did stand and walk a bit)and he said all reflexes were good,he looked healthy but seemed not quite right on his right side. He gave me an anti inflammatory (which is fun to give him I will add...) and told me if he was better he could swim but keep him somewhat confined. (He has a gigantic dog crate right now... We just got done building him a huge "condo" but haven't put him in yet.) He has been good the past few days still a little funky getting up now and then but much better. We let him swim a few minutes ago and the same thing happened. I warmed him with a hair dryer (which I have done since he was younger) and again he seems fine except cant walk. If anyone has any advise please help me and Henry... We would appreciate it!
