I am in Illinois too, half way between 2 Farm and Fleets. We go there a lot to pick up our chicken/horse/farm supplies. I was just there three days ago and picked up a few chicks. They have signs saying they are from Cackle Hatchery. If I can remember right, they had Black Jersey Giants, Buff Orps, Cherry Eggers, White Austra, Red Star, Barred Rock. Those were all pullets. Then they had some polish, and a few Booted Bantams. There might have been another kind of pullet, I don't remember. They had chicks a few weeks ago, this is a new batch. There were quite a few of them.
I picked up the remaining 5 Booted Bantams. There was one in there that didn't look so good, but I couldn't leave it behind. It was dead two hours later. I gave it a small drink when I got home and put it in the brooder right away, but it didn't work. I also picked up 5 Buff Orps. All the rest are doing great. They sell them in lots of 5. I am not sure if you have to buy 5 of one kind, or if you can mix them up to make 5.
I didn't get any of them last year, but the year before I got a few. I think I sold most of those.
