Actually maybe
@cfonts is in the best position to talk about heritage breeds - I was interested in finding out why so many chickens have survived there and it's because Kauai has no mongoose, unlike the other Hawaiian Islands. If I am gathering this correctly from some very brief reading, it is thought Polynesians brought Red Jungle Fowl to the Hawaiian Islands ages ago, and Europeans introduced some modern chicken breeds, but mostly the wild chickens grew in numbers after the '82 and '92 hurricanes where domesticated chickens got loose and lost. So there's interesting research being done with DNA analysis of the chicken populations there, and it's possible that Kauai may turn out to have an important pool of preserved Red Jungle Fowl genes that could be helpful to the rest of the world in bringing some sanity and health back to the world's over-bred and in-bred chickens. Apparently the remaining Red Jungle Fowl in their "native" places are suffering from lack of wild places to live and the introduction of domesticated chicken genes.

Chicken tax for Mugshot Monday. I don't recall if I've posted this one before. From early February. Once again it is Hazel I think (and Queenie in front).
@featherhead007 - I have figured out what it is about Hazel, and maybe it's a Buckeye thing - they have a strong brow, with full feathers. They look quite studious and serious, in a way. So when they are intent on something, their expression is extra-intense! (Or they look like they're mad at you

)

It is interesting - Hazel has appointed herself Patroller of Queenie, but I also find them often foraging together quite peacefully. Maybe that's self-interest on Hazel's part? Queenie grew up free-ranging, so maybe they know she knows how to find things. They do all instantly rush over when they think she's got something.
Things are fluid and not set in stone, but Popcorn and Butters are generally thick as thieves when foraging, more so than any other pair. I call them Partners In Crime. Peanut floats between these groups.
