Went out to their coop Tuesday morning and found one of our 5 week old chicks on the ground of the coop huddled under the step. She was very weak but waddled towards me. I put her in the house in a plastic bin with fresh food and water and heat lamp. Immediately I noticed blood on her beak and some oozing on her side. I originally thought she had fallen from the upper portion of the coop but then wondered if the other chicks had pecked her. My husband was checking her out and found a sore stretching from her under her wing to her butt. She is doing much better; walking around some and eating and drinking. Any ideas how this happened or anything that can speed the healing??
