I have an easter egger that had a rumble in her lungs a few weeks back. I have been giving everyone garlic powder in their food and ACV in their water ever since. She's gotten better (not completely, though). Now a handful of my other chicken have the same snotty nose issue. Everyone is acting completely normal, they just have a crust around their nostrils, a mild cough/sneeze, and a big bubble coming out of their nostril. All symptoms are occasional. Not all birds have them all, or consistently. The EE that was the first to show symptoms also has weirder poo than the others. I took a picture this morning. There are no worms in it, it's just a different consistency than the others. I'll find other birds have poo that look like this occasionally, but the EE's looks like this all the time, and has since I got her 2-3 months ago. What are your thoughts? I've done a ton of research and am stumped. I don't want to give the whole flock antibiotics if it's unnecessary. I also have 3 ducks. Everyone is in the same 75'x75' fenced area. They all share food (in a metal bucket feeder) and water (from a hen hydrator to keep it clean from the ducks, and they all drink the ducks' pond water. Ew.), but don't share sleeping quarters. The ducks have never shown any symptoms.
