I left for 3 days and when I returned my ducks Were acting Funny, They ran up to me. (which is crazy in itself Im the Bad man to them With Big scissors) I noticed first one duck constantly rolling his neck back almost as if he was having a spasm. then I noticed another one in the back doing the same thing. I called out my wife and kid to help me herd them and pin them in a fence so I could observe them. Sure enough all of the ducks had some kind of twitch either in there wings or necks or chest. I have them all penned up for the night till I go to the vet tomorrow. I quickly did a run threw of my farm to see what was out of place or not right. (left the farm with the girls and Friend) Only thing i noticed is there night time pool hadn't been dumped for 3 days its shallow it was horrid and almost like syrup. I quicky cleaned it out and sprayed them for about an hour letting them drink tons of fresh water from the hose. I cleaned and disinfected there pool feeders waterers cleaned there bedding. did what I would do If i didnt leave. I know the doc said he thought it was avian chorela or something like that he said he could treat them. (we only talked on the phone) Is this something that anyone else has experienced and is it worth spending the money on a meat bird I don't even have much invested in? are they gonna die even if I get them some meds? if anyone has any anwsers I sure apreciate them thank you. P.S. there all adults!
