Came in to the coop this am and one of my barred rocks is obviously ill. She is listless and is keeping one of her eyes closed. I syringe fed her some electrolyte water and we now have her isolated inside. She is not happy about this and is now shrieking in disagreement about being alone. I fed her some mealworms which she is eating and she seems a little perkier now. Should I keep her isolated even though it stresses her out? Help!
