I had one several years ago. Her name was Eggnus. When we purchased her she was suppose to be a white rock but the older she got the more my husband questioned her breed. He kept saying she looked like a meat chicken, the cornish x. She grew so fast and she loved to eat. I did not ration her food because I still thought she was a white rock chicken. She was one of the most special chickens I have ever had. She free ranged with the other chicks she was purchased with. At about five months of age her legs could not support her weight. I brought her in the house and improvised a sling for her. I tried to limit her food intake but I think it was already to late. The heat was so hard for her even with air conditioning I had to have a fan on her all the time. She lived to be about 8 months old. She never regained the ability to walk any distance. She never gave up she was truly a remarkable chicken. She lived to be about 8 months old. I loved her very much and still miss her.
