From the point when I got my hens (from a slightly sketchy farm) they've occasionally made kind of gasping/coughing/choking sounds, especially after eating. I kind of accepted them as normal as it hasn't gotten worse over time and they've all been gaining weight as opposed to losing them (they were really skinny before) and acting healthy otherwise. Does this sound like gapeworm? Should I deworm them or leave it? All their poop is normal, egg laying is normal, breathing is normal, and they're acting energetic and haven't slowed down at all.
