Our3 year old blue laced red wayandotte is off his game. It's been about a week since he crowed (otherwise he crows all day -- the silence is deafening), his wattles are getting paler. He seems slower than he normally is. And he spends more time inside the coop during the day than normal. And his tail is drooping. He doesn't give the "warning" calls that he used to do when we go out at night to shut up the coop, his heads up to the hens that something is up. What should I do?
