I have 11 chicks about 4-6 weeks old, one last night was on its back. We thought she was dead but she wasn't, after research we believe she has wry neck. She tucks her head under her body and walks backwards continually. She hasn't eaten anything because it seems like she doesn't have control of her motor skills. She drinks water like she's thirsty and then throws it all up. We have put vitamin E in the water per another article for the wry neck and she pukes it up. I feel like she might not make it through the night as she is very weak. Please help.
