I have a sweet silkie roo who I've had since he was a chick. He is about 2 1/2 years old. He lives inside because roosters aren't allowed where I live. He gets a lot of monitored outside time with the lady silkies and has free rang of my house. He usually crows a lot but lately he hasn't crowd at all. Not once in the past week. He hasn't been as lively and when I take him outside he just goes back in on his own. He is eating and drinking normal but does a lot of sitting and sleeping. I'm worried about him. I know living indoors isn't ideal for a chicken so I have always gone above and beyond to make his living situation pleasant. And again, I give him as much outside/social time as possible. Is it because he has become unhappy, or could he be sick?
