I have a year and a half old sebright hen who has never laid. Three days ago she suddenly turn ill on me. Ruffled feathers, extreme fatigue, drooping head, not eating or drinking, diarrhea that is more of a slimy clear/green discharge. She now has what appears to be the beginnings of a prolapsed vent from the diarrhea. Loosing weight extremely fast. Giving her wet mashed food and vitamin supplement water. someone please help me save her if i can.
