So, I have several chickens who are having a watery discharge from their nose. It's not constant. Just occasional. Nothing else is going on. No swollen face, wheezing, coughing, still eating and drinking with great enthusiasm and showing a normal energy level. I first noticed this last week with two chickens. I immediately separated them. Just notice two more today. One showing a "dirty" looking nose (Looks like the nostrils were wet and got dirty) and one having a small bubble from the nostril. What should I do to treat this? Does it need treated? Would they have gotten worse (the ones that have been separated since last week) by now if it were something to worry about? I'm not against medicating, but I don't want to medicate if it's not necessary. Any advice is much appreciated. This is our first year with chickens and I'm still learning when I need to panic and when I don't.
