No expert here in chicken first aid - just an old EMT. While waiting for a chicken expert to jump back in - did you do the internal exam that @Tycine1 described above? If so - what did you feel. Don't worry about stuffing the prolapse inside yet - just help the more experienced diagnose what's going on and they'll be more able to offer advice.
