Hello, I am new to chickens and have a sick chick. She is lethargic, weak, and barely opening her eyes. I purchased her Friday, and was weak, but she perked up until this morning with electrolytes and water through a little syringe. Also we have been feeding her a mash through the syringe with yogurt and smashed up chicken starter. I also tried poly vi sol as well. Today, she is worse than she has been and barely drank or eaten. Does anyone have any other suggestions for my little girl?
