Hello all, I have an older duckling, born on April 21st, who has some concerning symptoms and I'm hoping I can get some help. Unfortunately I can't provide photos for at least a couple of days, but I'll do my best to describe all of his symptoms and situation. I hatched this guy, Pen-Pen, from my incubator. He is a black swedish/rouen mix from my own birds. He has grown fairly well for the most part and been pretty healthy, and he had no physical symptoms or deformities when he was young. I have been raising him on Flock Raiser, which I have always used on ducklings with no problem. He did live inside for much of the beginning of his life, as he is imprinted to me, but as he got bigger he started spending more time outside and now he lives in the coop with my chickens, ducks, chukar, and guinea fowl. When he was around four weeks or so, I noticed he was limping, seemed a bit weak, and had weepy eyes. His appetite also went down. His father had chlamydia psitacci when I rescued him and I successfully treated him for that, but I decided to wait a little while longer and see if the symptoms persisted before going through all the difficulty to get the medication for him. He has days where he's great and days where he seems worse. He seems to be weak, limp, and not have much appetite at random. Most of the time he walks around fine and eats well. His voice seems a little low/hoarse, but other than that he was doing great. Then I noticed his neck was curving strangely off to the side. It was just slight for a little while, but now I left for six days and came back and it's gotten a bit worse. He still eats well, has clear eyes, is alert, and walks fine, but his neck is definitely crooked off to one side. I'm afraid it's going to get even worse and cripple him. I've massaged the neck and it doesn't seem sore or swollen or anything, just twisted off to one side abnormally. Could this be a result of chlamydia psitacci, or does it sound like something else? Could it be some sort of deficiency? I love this sweet little fellow, I really want him to get better. If it is chlamydia, I know how to treat him, but I don't want to give him the wrong medication if these symptoms match better to something else. The other symptoms he exhibited made it seem like it could be chlamydia (though he doesn't have all of the right symptoms--his poop isn't extremely watery, and his dad got so weak he couldn't stand after a little while and this guy is still fine to walk and eats well) but the whole neck twisting thing is really concerning to me and is unlike anything his dad had. Anyone have ideas as to what this could be, and how to treat it? I'll go to the vet with him if I need to because I care deeply for Pen-Pen, though I would rather not if I can avoid it. I would really appreciate some input from you duck experts--I am really hoping there's a decent prognosis! I can and will take care of him if this curvature of the neck can't be fixed, I'm just afraid it's going to get worse.
