Good luck, and don’t give up hope. But don’t separate your baby from all of the other chicks. Put at least one trusted baby in with her. When I had a chick who wouldn’t eat or drink, I had her inside for 3 days, literally putting a mixture of Gatorade and her food into her beak, and she finally would swallow it. But when I had another chick who got henpecked, I put the two together and that sickly chick started walking, eating and drinking!!!! No baby wants to be alone. Keep up with the hope. My two chicks are best friends who keep each other safe in our flock of 10. They’re 8 weeks old and thriving! Cheers!
