I didn't realize just how different chickens can be from one breed to the next in terms of temperament and behavior, especially if they came from the same list of "best breeds for pet chickens" that were ranked high for families with kids... I got two from one such list - Orpingtons and Barnevelders. They were both lauded for their pet chicken qualities and tolerance of kids. While some aspects are shared between the two breeds - they are both low-pecking-order and non-confrontational, calm breeds - they vary greatly in how well they fit in a family with kids. We hatched all of them in the house and my kids were heavily involved in the process, handled all the chicks extensively and basically spent all of 2020's COVID summer playing with the chickens when school was closed. You can't get more socialized than that. And yet... The Orps are total sweethearts that don't mind the kids picking them up and carrying them around, putting hats on them, rocking them to sleep etc. The Barnevelders, on the other hand, won't let anybody touch them. The most they will do is hop up in my lap and keep me company for a while, as long as I don't lay a single finger on them. They won't do that much with anybody else. I spoke with their breeder and she said that hers won't even let her get close, and that the lap thing was a total achievement on my part... So, the lesson I learned is: don't trust internet listicles.
