I brought home some olive egger chicks yesterday and one was noticeably quieter and weak. She would fall over when bumped, is very lethargic, not eating or drinking unless I do it and today I found her on her back and notable to get up. She was shaking and looked like her feet where clenched and seizing. I gave her some gatorade for electrolytes and a little boost, but she is still very tired. I keep her on my lap in a blanket and a heating pad. I've read that I can try to give catfood? What else can I do?
