I just came home from a week long vacation (responsible friend feeding and watering) and my 24 week old hen Mrs. Pigglewiggle just isn't right. She lays down all the time and closes her eyes a lot. Sometimes her head droops when I hold her. Her poop is a bit runny, clear and white. She started laying a week and a half ago (I think it was her). She gets laying mash mixed with oyster shells and veggies and fruit for goodies, though she hasn't gotten the fruits and veggies for the past week because I've been gone. It has been fairly hot here but she has had access to shade and fresh water. I opened her beak and gave her fresh water when I got home an hour ago, and have separated her from the other 13 hens (no roos). Should I be forcing her to eat something? Any suggestions would be appreciated as this is my first flock.
