I feel the same way! Silent bob follows me everywhere and is very gentle. If he hears me say his name or "baby bird" he comes running. He wasnt much over a day or two old when I brought him home, he still had his egg tooth. I love my chickens as well but they couldn't care less about what I'm up to, unlike bob. So glad your boy is doing well!
I wanted to commend you on using your own investigative power to get an answer! If you are sure of which hatchery they used, then you are probably correct on the breed. My guess is... that he will live his best life for just as long as possible. And as many have noted, it could be longer than we think. I have a couple BBW in with my heritage poults, and WOW is there ever a difference in size at only two weeks old!
