Hello, everyone. I am posting because I am concerned about one of my chickens. A few days ago, I noticed that she would jerk her neck upwards as far as it could go, sometimes in a quick succession. I also noticed that her breathing sounds quite funny. Below I have linked a video. You might have to restart the video a few times, because she does the neck thing at the very beginning. Also, if you listen closely to the squeaky noise that sounds like an old swingset, it's her breathing. I should probably add that she is a year and a half old. I don't know if this could be worms or possibly respiratory problems, but I would appreciate any help I can get. Thanks, Dillon. Edit: After doing some follow up research, it appears that you need a different kind of medication for each kind of worm. In my case, I thought my hen had gapeworms, but I used Wazine 17 which I later found out is only to treat roundworms. I urge anyone who may come across this thread on Google(or BYC) to make sure you have an idea of what kind of worms you are dealing with before you purchase any dewormer. Although the wormer I used was for ringworms, my hen still seems to be doing better. However, I am going to buy a different treatment that is used for gapeworms, just to be safe. Also, make sure you do a follow up treatment between two to four weeks after the initial treatment.
