Hello. My 5 week old Rhode island red has been puffed up and lethargic for a couple days. She is inside and isolated now, but had been getting some outside time and allowed to forage in her run. Her poop is small and watery, and her crop is still present (I don't know how big it should be) and it's soft. I tried turning her upside down and milking it last night, but only a little bit of clear liquid (water) came out. We are amateurs! They have not been eating medicated feed. And I'm worried the grass was too long and they don't get enough grit. None of the other birds seem sick. I know there are other threads about this but I just felt like I needed personalized advice. Thank you!
