Somewhere recently I read a story of a young woman who raised a house rooster in her apartment because he was orphaned and he goes everywhere with her. She's his everything, and there was never a question of putting him outside with a flock of hens. I believe fate (or God- whatever you want to call it) sends a special animal into our lives. If he seems healthy and happy, you're OK with him in the house, and he clearly refuses chicken companionship, enjoy your time with him!
