Our local TSC (Lowell, MI) gets their chicks from Townline. I think several of the TSCs and other places that sell chicks in the spring do too.Townline Hatchery in Zeeland Michigan. It is family owned for over 100 Years. I have ordered online and been happy. I also found a nearby store that sells them. I would go there rather than TSC.
I once called them to see if they had Blue Australorps. No, do not, never have. The guy who answered the phone was VERY knowledgeable about their breeds. He definitely wasn't "Just someone who answers the phone and takes orders."
