I noticed the other day one of my 4-week-olds had one goopy, closed eye, and that one of my 8-week-olds was having gurgly breathing. The younger chick doesn't seem to be adversely affected and even seemed better today. The older chick's breathing got a bit better (less struggling) but now it has goopy eyes. I checked out all the "kids" at lock-up tonight and there are a small handful of others with varying degrees of these symptoms. I brought a couple in just to clean their eyes and then put them back to bed. The adults are totally fine. Is this just one of those things they have to go through in growing up, like how we grow up dealing with the odd cold or flu? Or are these signs of something serious that needs attention asap? I'm kinda leaning towards the former, considering the fact that the grownups are fine and probably already had what the kids now have but I want to know what you all think just in case. I did search the symptoms and most of the threads I found weren't very informative except in which antibiotic to get and how to treat; this is a last resort for me, unless this IS something potentially devastating, as I'd rather allow them to be sick and get better on their own. Which brings up next question: anything I can do naturally in addition to free-range and acv to make the recovery smoother and faster? Thanks!
