I have been watching my chickens for the past two weeks. I noticed some sneezes and head shaking. There is absolutely no signs of progressing respiratory infections. No wheezing, rattles, snotting, bubbly eyes, lethargy ect. I had even bought Tylan injectable just in case antibiotics became necessary. In the past week I have noticed a few of them doing that yawning thing. The more I am watching them the more I am thinking gapeworm They are acting fine; eating, drinking, causing mischief. Just this occasional sneezing, head shaking and yawning thing. I read that Ivermectin is the thing to use for gapeworm? Is the oral equine paste okay or does it have to be the injectable stuff given orally? Or is there something even better out there? Thanks in advance ~Steph Oh and it's only limited to a few of my cluckers. Not all of them are doing this.
