I asked, and the guy said they get them from Townline in Zeeland, MI, which is probably close enough they truck them in (?). This TSC is in Lowell, MI, about an hour away from the hatchery.Does your TS get them from just one hatchery?
I looked at Townline's website and there is a "Current Availability" tab, so you can see what they have. They guy said they couldn't take my name and call me when they get Blue Australorps, or they'd be doing that for 500 people. I understand. He said I could call them on days they get chicks to ask if they're in.
I hope it's not for about 6 weeks, unless I have a broody before then.
