I am also new to this chicken thing... Only six weeks along. So far our Black Austrolorp is the most gentle of the flock - She just stays still and waits to be handled. She seems to understand foraging better than the rest. She will practically climb into an offered jar of food, tilted her way, to have it all to herself. She also seems to enjoy being tickled under her wings. What I mean to say is... She is not timid, nor is she bossy or aggressive.
Sweet, gentle big bird is a good description!
So, I'm almost 10 months in to this chicken thing. We lost one (Florence, Silver Laced Wyandotte), and adopted 3 more pullets. One of the new gals is another Black Austrolorp. I really planned on having no duplicate breeds... But Minty (#1 BL) is such a great gal, I couldn't resist adding another to the flock. While all of my hens are super easy to handle, Minty and her breed mate Raven are as cool as you could get. Minty has also turned out to be one of the 2 best layers... Astrid (Buff Orpington) is the flock leader and the other top layer.
Astrid helps me garden when the weather is nice (gonna be awhile!) and is always on top of my hay fork when I turn the compost for them. Early bird really does get the worm. Of the rest... Chipmonk and Dove are Easter Eggers. Nellie is a Golden Laced Wyandotte. Good layer until the days got short. June Bug (we named her Ginger, but she prefers June Bug) is a New Hampshire Red (?)... June Bug colored feathers with a black tail. And then there's Dot, a Barred Rock of some sort. Dot got sick shortly after the 6 week old mark. She spent a lot of time on my lap in the summer drinking extra antibiotics from a syringe and later, eating meal worms and other treats from my hand. She is huge... And Gentle... And follows me around to be first for food and treats... But she has never laid an egg. Such a great hen, I didn't really care.
Just yesterday, Dot squatted right in front of me for the first time! I'm thinking she will be giving me her first egg pretty soon!!!
Since this thread is about the best breeds for children... I'm thinking that it's all in the way you raise them and interact with them. We have 2 kids that help tend the flock and play with them. When friends come over... We might pull a few off the roost at night and just hold them for a bit of warmth in the dark on the patio. And when the weather is nice, neighborhood families bring the kids by to see if the chickens are out. If I am out with the girls, I make an effort to pick one uo so the kids (and parents) can pet her and just be a little familiar with chickens. I make a point to spend some cuddle time with each of the girls each week. Just hold them and pet them and talk to them.
Anyway... I wouldn't trade any of them and with very little work, they are all quite gentle and suitable for kids.
