I only have four coturnix in a pretty roomy cage. Yesterday one of the females started acting extremely oddly and just hunched down feathers up and barely moved for anything. I brought her inside today to keep an eye on her and she almost acts seizure-like, head whipping every way and rolls around or gets stuck on her back. She backs up a lot and spins in circles and seems very uncontrolled. The poop is either off-white or is a dark green. She won't eat or drink or not that I have seen anyway. I don't know much about quail diseases but does any of this sound like something specific? I would sincerely appreciate any direction or guidance, thank you!
