Tony, if you are still checking this thread, mypetchicken.com has a minimum of I think 3-4 chickens. You end up paying more than buying 25 from another hatchery because of shipping and warmers to make sure the chickens live, but I know you were looking for a smaller amount of chickens.
I am hoping to get to tractor supply next week early to get all the supplies for my brooder and talk to whoever is in charge of ordering chicks. I want to pick his/her brain about what they will have and if breeds will be identifiable. If not, I want to see if they will add the chicks I want onto their first order, which now is supposed to be coming March 17th.
