the ideal chicken

We are starting a small homestead just south of Cincinnatti, Ohio. I plan on having chickens and have read a few posts that mention winter hardy birds and such. I would be grateful for some good ideas on breeds that would accept the kind of winters we have up this way. It will be a little while before I get that part of the homestead up and running but would prefer to learn from others' experience rather than wasting time and resources. Anyone have favorites for zone 6 climates?

Any standard chicken breed will do just fine in a zone 6 climate.
Birds do very well in cold, just remember those little cardinals in the snow.

You just need to take care of some winter precautions.

Don't use metal for roosts. Nest boxes would be nice if they were made from wood as well.
Throw some straw or litter down, if you want, but they won't really nest in it much. You'll just feel better knowing you offered.
Make sure you supply them with water than is not frozen.
If you really want to feel good, hang a light bulb down from the ceiling, low.
It will put off heat and increase your lay a bit.
You can seal off any breezes, but make sure it gets ventilated. Chicken houses can produce a lot of sinus-burning fumes.
