Alright so I have a Americana Chicken. She just finished molting and she is normaly the top chicken, but she was getting picked on. She has lost tons of weight and is shivering. She has tons of food to eat crumble/corn but she is skinny as heck. I have never felt a chicken this light, and for a americana this is crazy. Does she have a problem or do I just need to find a way for her to eat some food? PLEASE HELP!
