We picked up eleven Australorps chicks that are just a few days old from a friend who purchased them from a hatchery, but changed his mind and wanted EEs instead. They are less than a week old and had been in his barn. One of the babies is scratching and chirping so bad. She keeps falling to the floor scratching both sides repeatedly. I put her body into a DE bath and she shook well but continued to scratch. It looked as if she was gonna scratch her eyes out. I took her to the bath sink and gently cleansed the head and neck with warm water and dried. No change. Any suggestions?
