Hi, I have a 2 month old chick that isn't eating or drinking and is quiet and lethargic. She is fine as far as breathing, no respiratory symptoms or anything like that. She just sits puffed up and not real interested in eating. I have separated her from the group of chicks and syringed in some water and she pecks at bread I have offered her. She is not interested in her crumbles. I added another dish of wetted down crumbles in case that entices her at all. I feed medicated chick starter crumbles. None of the other chicks seem sick or have any problems. Her croup is empty. She is having soft formed brown poops, not liquid or bloody or anything like that. She is strong enough to really clamp down hard when it comes to me syringing her any water. Does this sound like something I should just try antibiotics? I have never wormed this batch of chicks yet and hate to worm when she's sick... or should I? Any ideas?
