I'm no expert of smartness... I have a few that show a little more smarts than others, With that being said... I can compare personality between Hatchery chicks and Incubated chicks. Currently in my flock, My older girls were all hatchery chicks, they were ok growing up, but never that follow you around kinda chick. My seramas follow me around the yard when I'm outside with them, and my last batch of mixes, I have to watch were I step. Infact if my EE roo gets going, my seramas (minus my serama roo, who got mounted today..lol) will jump up on me. Both the seramas, and my 11 Heinz 57's were all hatched here. I have 2 from that batch that seem to enjoy being picked up. Not so with my hatchery girls.
