I agree with the Easter Eggers. My grands love them, and the colored eggs are a bonus! You'll often find them in feed stores incorrectly marked "Americanas" (or any other misspelled version thereof) or even "Aracaunas". In reality they are just plain, good old Easter Eggers, and I have such a soft spot for them! Just in case you'd like to meet my older girls here's a link with some photos - I have two more of them now.
I also have some Light and some Buff Brahmas, which I have found to be very pleasant, gentle birds, along with a Buff Orpington, some Red Sex Links, and a couple of Cuckoo Marans. I've never had any issues with any of them where the kids are concerned. I had one rooster that we hatched here, and the first time he went after my hand he was in the freezer. I can't afford to have any bird out there that might hurt or even scare my kids.
I have two disabled granddaughters and obviously I simply can't have any chicken out there that I don't trust 100%, especially since Katie, the oldest at 10 now, is my best, most reliable chicken sitter when we are out of town. Her little sister Kendra is in a wheelchair, although she walks at times with braces and assistance, and she loves being out there with the chickens. And I've said before, if I was allowed to have only breed/variety of chickens, it would be Easter Eggers.
Good luck with this wonderful new adventure if you decide to do it. We didn't plan on having chickens, it just sorta happened and now I can't imagine not having them!
