We just received our first chicks ever yesterday, from a March 2nd hatch at Meyer. All 15 of them have been getting on great until this afternoon, when I checked on them and found one laying down, eyes shut, not really responsive. She won't open her eyes, eat, or drink. I checked her and thought she had pasty butt, so I was wiping and trying to get it off until I realized that her vent was fine, that it was something else that looked bad on her belly/underside. A search online led me to believe that it's a rough navel, but I don't know how bad it is, if it's fixable, or what to do to treat it. There's no bleeding, her poop looks normal to me, maybe on the runny side. I've separated her from the rest of the chicks in the brooder into a small box with her own food and water. Thank you for your help!
