I have a four month old hen silkie that was a surprise, baby, and due to health reasons of my own I was not able to take her out and acclimate her with the other chickens and the weather. Been colder here than usual about two months ago she started screaming, shaking her head and walking/falling backwards at the same time. And she will just shake her head. I’ve tried corrid I’ve tried adding vitamins to her water but I don’t know what else to do. She’s very friendly my grandmother sits and hold her and loves on her a lot. Can anybody help?
