Hello, I have a very sick hen. Yesterday morning I found her in the coop very lethargic and hardly moving with eyes closed. I picked her up and was horrified to see how thin she was. Her keel is very sharp and you can see it protruding when you move her feathers away. I brought her inside and was pleased to find she was eating and drinking. I gave her some yogurt soaked bread as well as some electrolyte water, and kept her warm. She perked up and was walking and clucking around the bathroom by yesterday evening so I put her back in the coop. I checked on her before work this morning and she was more lethargic but still had her eyes open and seemed to be content resting in a nesting box. When I came home, I found her out in the snow, she must have gotten outside and not been able to get back in, and to make things worse, the other chickens pecked her almost to death while she laid in the yard. She is now back in a tub in the bathroom, I have treated the pecking wounds to her head as much as possible with saline solution and bactine. She is still alive but will no longer eat or drink and struggles to sit up. I can't find her crop, so it must be empty? Is there anything else you suggest doing to give her a chance to recover?
