I have a standard blue Cochin Rooster that is gentle as a lamb. He is 5 years old. About a month ago he started walking like he had a sore foot or joint. He would just stand or lay down and watch his hens from a distance. After about a week or so, he started walking normally although slowly. He has been crowing less and isn't chasing his hens as much. For the last few days, I've noticed that his comb as becoming dark purple and his wattles are dry and dark red. He either stands with his eyes closed or lays down and droops his head with his eyes closed. When the eyes are open, you can see the inner lid when he blinks. Today, he couldn't jump up to roost with his hens and he allowed me to pick him up and place him up with them. He has little appetite and has lost weight. Does any one know what the problem could be? Is he just getting near the end, or is his sick?
