Can't believe it's been three years since I posted to this thread. Time flies!
I just have one Brahma left of the original triplets. Lady Di is still tame and affectionate, though no longer laying. She's been permitted to retire in dignity.
My tame Wyandotte Irene has gotten less tame, but not less mean and bossy. She is quick to peck anyone I'm hugging and who is incapacitated by my delivering of affection.
Almost my entire flock of fourteen hens and one rooster is very tame, and more so every day, it seems. The more chickens are handled, the more comfortable they are around people. Even my rooster, who didn't start out as a hug-a-bun, is now demanding to be included in group hugs along with half a dozen of his girls.
I think that people who "want" their flock to be just tame enough to be easily caught when necessary, are content to have chickens relegated to being egg and meat producers and not pets, which require more time be invested. I'm definitely in the "chickens-as-pets" camp. The rewards can't even be tabulated.
