i noticed one of my hens laying down and I went to pick her up and she was skin and bones. I brought her in and gave her water with a syringe then forced fed her some dog food trying to get some nutrients in her. That was last night. This morning there is no change. I gave her more water and dog food. Still no change. No poop at all in her carrier. Her feathers are puffed out and her eyes are closed. What can I do for her?
