Hello all! I came home today and noticed one of my hens was sitting down moving her head really oddly when she would walk. Shes really weak a sluggish. I seperated her gave her food a water. I did put some chicks down last week thst id gotten from a lady who seemed like they had possible MG.... Is this MG or an attack from a predator? She has a really red raw area by her ear and is missing feathers around her neck on the same side? Please advise!
