My Bella, golden laced polish, is sick. She is very thin, you can feel almost every bone in her body and her crop bulges out all the time. She barely every clucks anymore when she used to be the loudest of the flock. I can fit my hands around her. Is there any diets a chicken can go on to make them fatten up? She is my baby and will be devastated if she dies. Please help me! I also believe she has lice so if that has anything to do with it, or not, is there anything I can do for that?
