Yeah, they tend to have less connection because of all the process of going from hatchery to store, and the lack of interaction before they get bought. They'd be fine layers, but less fine friends.

And breed factors in too. The ones usually out for sale in a store will be bred for laying or meat, and that means no attention to more than bare docility. Some breeds though, they're known for being friendly rather than just calm. We have a marans that prefers human company to other birds most of the time. Since she was also hand raised before we got her, I'm not too surprised she tends to amaze people with how friendly and loving she is.

I think if you get more, find a local breeder and you'll have way better luck
