One thing to add ... you folks doing breeding projects and maintaining your own 'barnyard mixes' do so much to further the cause of raising chickens. Granted, as this thread has made clear, there are so many different things people want to get out of their chicken experience. In some cases, chicks from Tractor Supply or a big-time hatchery fit the bill. But, it's the local mixes that, over time, can really become the perfect fit for a location or a desired 'chicken use.' It reminds me of getting great heirloom beans from a local gardener who has been carefully savings seeds year after year.
I wish I could contribute in that way, but alas that's not feasible for me. My hope is when i buy my next pullets, they will be from somebody making their own barnyard mix nearby. I've seen some options on Craigslist, but I'm not ready to pull the trigger yet. I guess that's a contribution in a small way.
