Hi I'm new to the site today and wondered if anyone out there give me some advice please? One of our 8 month old highbred chickens is hunched up, listless, very, very thin, pale eyes, can't feel an egg in her vent with my finger but she's not laying, no lice, is eating, drinking and pooping fine and her crop is emptying ok so I don't think it's sour crop. Have given her poultry spice, a warm bath and have just starting on wormer. I've brought her inside to keep her warm and keep an eye on her. She's been this way for three days now. Any other ideas please?
