My house chicken, a partridge silkie I bought at a poultry show last month, seems to be losing alot of her feathers. She lives in a dog cage and has food and water, but doesn't seem happy. All she wants to do is sit. She also seems to have seizures every few days-she squawks like she's being attacked by a predator, and sometimes will roll on one side or pull her head back. Seconds later, she's fine again. I thought it might be a disease but she doesn't have any other symptoms. Anyways, could she be molting in the winter? According to the breeder she was about 3-4 months old when I bought her. Would that be causing her to be depressed?
