Hi, I am very worried about my young Polish (I think it’s a rooster). This morning I went to let out my chickens, and he/she didn’t come out. At first I thought he/she was dehydrated as it has been hot here lately, so I gave it some cold water and sat it near the fan for a bit. Now he/she is in a spare outside pen, along side it’s brother/sister (they are the same age). He/she has been gasping, and making a high pitched, loud cough-like noise, almost like a honk. They also shook their head quite roughly once or twice. I gave him/her some general, diluted worming liquid, but I’m worried if it is gapeworm that this worming liquid won’t be enough to get rid of the worm. I am also wondering if I do purchase some gape worming supplement, if I should give it to the entire flock just to be safe? Thanks.
