I once found a love bird at my bird feeder. I managed to attract him with some seed, and kept him. I realized he would be lonely with me at work all day, so I gave him to my retired parents.
People will say a love bird without a mate will die -- even their name says they need a mate. But this one lived a long, happy life all alone, but not really alone because he had companionship all day, in the form of humans. He did birdy things, like preening and humping things, but he was absolutely happy, as Hei Hei is.
Good luck with your beautiful boy! If you and he are happy, why should you change anything? He has companionship, and he can do his birdy things. That is enough for any social creature. I haven't had chickens for long, but I've had birds for most of my life, and I often thought that if chicken poop was just a bit smaller, I'd have one inside. Personality-wise, they're like other birds, just bigger.
