We have a one year old rooster who is big and looks perfectly healthy. Three days ago I noticed him standing up and "sleeping". That night my husband wask woken by the dog to go outside and pee at 3am. So my husband took the dog out and found Roo Roo up and marching the pen. We bougth thought this was weird. And now it is the third day and Roo Roo is still sleeping. All day long. Is this normal or should I be worried, as I'am?
