I also have a meat chicken, her name is Lucky, she is about 8-9 months old. She is so fat she can’t hardly walk. I’ve got her by herself so she don’t have full access to the other chickens food. I googled how to make a chicken loose weight, it said 16% protein and low calories. I have given her this food and controlled how much she eats a day for about two weeks, she still can’t hardly walk. I’m not sure if she’s losing any weight. She is the best chicken that I have very sweet. I don’t know what else to do for her to help her lose weight. She just can’t hardly walk around at all other than that she seems healthy.
