Boy did you find the best place to learn about all things chicken!!!
Grab a roost and join in!!!
check out Cackle Hatchery. They come highly recommended. Great website with actual pics of their birds. My Aussie chicks should be arriving from them next week.
I would try to order from the hatchery closest to you. Not only is it easier on the chicks during shipping, but it is always better to have birds hatched in your area for health reasons. Good luck with ordering your new flock and welcome to ours!
