Hi - first time chicken owner here One of my pullets (hard to tell which) has had yellow, foamy poops for 10 days. I did a quick google search and it seems colour/consistency points to diarrhea. Here are the details: -none of them are acting different then usual; they are all drinking water, eating, playing, perching as usual. -there is not a lot of diarrhea, just 1 or 2 every day I come home and look -they are in a chicken tractor which is moved daily from one patch of grass to another -they have a dust bath made of dirt and sand, and nesting boxes filled which commercial sawdust -we have been putting apple cider vinegar in their water, and giving them bits of yogurt -they normal eat a diet of growers crumble with some hen scratch, grit, and meal worms here and there Any suggestions? Should we be worried? Any advice is much appreciated.
