Proud to say I (somehow) singlehandedly managed to look down my hen's throat. With my headlamp shining in I saw something that seemed strange: the opening through which she was breathing was a hole only half the width of her throat; the rest was closed and yellowish/off-white. Is that normal? The backstory: I was looking to see if she has gapeworms (and saw nothing red). She has been hiccuping, wheezing, coughing for a few days, and it seems to be getting worse. She has 100% of her appetite and doesn't seem listless, just unable to breathe properly. When I felt her neck there was a hard spot where I think the crop should be, but I don't know. Nine-month-old BO who free-ranges and has been eating worms, etc. Help on any/all?
