Two days ago, one of my chickens was looking "off". She looked better yesterday, though, but today she's looking bad again. Her crop was small and a bit squishy when I picked her up in the morning. She's been laying fine. Found this in her poop today. Could this be a worm? She's an 8 month old RIR. Her sister displays none of these symptoms. She's eating and laying fine. She's scratching around in the soil rn. Could this be worms?? If so, what should I do? And if not, what is it??? Any help is greatly appreciated, and I'm really worried about her right now. So, anyone..please!!!
