He's grown huge and strong supplemented by local flora. I'm inbetween Seattle and Canada where the soil is dark and mineral rich. Our water is glacial runoff, worms everywhere. I did a breeding stock force reduction and only bred the 4 out of 17 chickens that survived a Coyote attack.
Offspring is bigger, better, stronger, smarter than parents, hybrid vigor...
