I've posted several times about my concerns for my rooster Kingy of 11 years old. He has problems with his legs due to old age. These past two days, I find him at least once a day, just laying on the ground on his back, his legs in the air, his eyes open. Sunbathing? I hardly see him dusting himself. Once I slowly tried to turn him over which he did, he stood up and walked away. Today, I rolled him over and he stayed there for awhile. I stroked him lighty (which he would never allow me to) until he got up but either looked like he was woozy, had weak legs, or something else. He ate well but still had a hard time reaching up to drink water from the bucket. What does this mean?
