Hi, one of my hens has been very lethargic. She is a silkie and went broody recently. When taken off her nest she would just sit there and close her eyes. She barely has enough energy to bock and won't eat. She now isn't showing any real interest in eggs. She usually rarely ever moves and just sits in the cornor of the cage I put her in with her eyes closed. I have been giving her water with garlic, vitamins, and sulfdimethoxine which is usually used for cholera and a few other illnesses. We have had a few rats in the coop which may have carried cholera but I am not sure if it really is this ilness.
